Heavy Oil Showdown:
Jackal Ghost V2 vs Combat Solid vs Wicked Gremlin

Heavy oil is simple until it's not. Either the ball never picks up and you push the pocket all night, or it picks up at 35 feet and you're already walking left in the fourth frame. It's September now, so we're taking a look back at the last month, one that handed us three new solids aimed at that problem. Motiv updated a ten-year benchmark. Brunswick put HK22C² on the Combat core and called it their biggest hook since the Mesmerize. Roto Grip wrapped the Gremlin’s maxed-out core in a sanded solid instead of a pearl.

They're all big on hook, but they're not three versions of the same ball. One rolls early and stays in an arc. One bites sooner and turns harder. One has more length than the other two and keeps driving instead of snapping. “Best” is the wrong question. The useful question is which motion your bag is missing.

Read	Early midlane, continuous	Earliest of the three	Later than the Combat, earlier than the original pearl Gremlin
Hook shape	Strong, smooth arc	Smooth hard turn, more defined move	Strong midlane, continuous finish — not a flip ball
Backend	Continuation through the pins	Powerful, continuous drive	Responsive but rounded
Best night	Heavy oil you have to live on for a block	Fresh heavy volume, or you need the ball to change direction sooner	Medium-heavy to heavy when a duller solid is too early
Watch-out	Can be more ball than a burnt house shot wants	The 500/1500 surface will use up a dry backend	High-rev players on a tight house shot can still get left

Same job, three speeds. The Combat is the dullest and has the highest intermediate differential, so it's the first to pick up and the most willing to make a move. The Ghost V2 is the low-RG workhorse: it revs early and just keeps rolling. The Wicked Gremlin has the highest total differential and the lowest mass bias, plus a 2000 finish instead of 500/1500, so it gets down the lane a little farther and stays smoother off the spot.

Motiv Jackal Ghost V2: The Heavy-Oil Benchmark

The original Jackal Ghost lasted almost a decade because the Predator V2 core did one thing well. Low RG. Big differential. Early roll. A fat, continuous arc that didn't die at the pins. Motiv left that core alone. The V2 change is the cover. The V2 uses the Leverage HFS, a high-friction solid built for the oil volumes people actually see in 2026, finished at 3000 LSS.

That 3000 grit matters. It's not a 500-grit sanded monster. The ball still sets up in the oil, but it keeps enough energy to finish through the deck instead of standing up at 40 feet and fading. Testers who lived with the original Ghost keep saying the same thing about this one. This ball is earlier and stronger through the midlane with the same shape they already trusted.

It's the safest “one heavy-oil ball” of the three if your schedule is sport patterns, fresh challenge shots, and the occasional over-oiled house pair. Two-handers and higher-rev players get the early roll without the ball quitting when the pattern starts to move. Speed-dominant players get help they can't create with a polished pearl.

Shop the Jackal Ghost V2 if that continuous arc is the missing piece.

Brunswick Combat Solid: The Earliest, Strongest Turn

Brunswick isn't being quiet about this one. The Combat Solid is the biggest-hooking ball they've built since the Mesmerize. Same Rampart asymmetric core as the rest of the Combat line. New HK22C² Alpha Premier Solid cover at 500/1500 Siaair. At 15 lb the numbers are RG 2.502, differential .051, and a .019 intermediate diff, the highest mass bias in this trio.

That combination is why the shape keeps getting called a smooth hard turn. It's not a jerky snap. It reads early, blends the wet/dry, and then drives through the pocket with a defined move. If your problem on heavy oil is that the ball gets to the breakpoint still standing up, this is the one built to change direction before the backends take over.

Speed-dominant players should look here first. The dull surface and the higher intermediate differential give you axis migration and traction you don't have to manufacture with your hand. Higher-rev players can still throw it, but they'll be playing deeper, sooner, than they would with the Ghost V2 or the Gremlin.

Leave the 500/1500 box finish alone on the fresh. If the pair is already used, 2000 or a light polish is the first adjustment, not a different ball.

Roto Grip Wicked Gremlin: More Length Than the Other Two Solids

The original Gremlin was a pearl. Clean fronts. Angular snap. The Wicked Gremlin keeps the same Rondure MaxD core (highest RG and highest differential that shape has carried) and puts a G-R1 solid on it at 2000 Abralon.

That's the opposite of a flip upgrade. Roto Grip’s own comparison is blunt. It has more midlane traction than the pearl, a smoother transition, and a more predictable, continuous read through the pins. Testers who've thrown both say the Wicked picks up about five feet sooner than the original and loses the hockey-stick move. Some have it stronger than an Alpha Crux remake through the backends once those start to slow down. Others on older wood or a tight 41-foot house shot say it wants to start hooking at 30 to 35 feet if you stay right.

So this isn't the “angle play” of the three. It's the heavy-oil Gremlin that can live on a fresh house shot and a medium-heavy tournament pair without the pearl’s late jump. The .010 mass bias is the lowest of the group, which is why the move stays rounded instead of violent.

If your current big asym is already too early, and a 500-grit solid would only make that worse, the Wicked Gremlin is the one that still gives you hook without asking you to stand in the same footprints as the Combat.

Which one should you actually buy?

Start with the miss you already have.

If you need the ball to roll earlier and just keep going, get the Ghost V2. That's the benchmark shape, and the 3000 finish is the reason you can stay with it after game one.

If you need the ball to hook more, and hook sooner, because your speed beats your revs, grab the Combat Solid. Dull surface, highest mass bias, strongest defined turn.

And if you need heavy-oil traction that isn't as early as a 500/1500 solid, add the Wicked Gremlin to your bag. It's the same family as the pearl Gremlin, with the snap taken out and the midlane put back in.

You don't need all three. Two of them will cover almost the same night and fight each other in the bag. If you already own a sanded high-mass-bias asym, skip the Combat and look at the Ghost or the Gremlin. If you already own a 3000-grit heavy-oil benchmark, the Combat is the step up in surface and the Gremlin is the step sideways in shape.

Skip all three if you bowl on light or burnt house shots most weeks. These covers were built to eat oil. On a pair that's already been through two leagues, a mid-performance hybrid or a polished pearl will score more than any of these.

All three of these new balls are asymmetric. PSA placement isn't a footnote. A pin-down layout tames the Combat. A longer pin-to-PAP on the Gremlin keeps the .058 differential from flaring into a roll-out. Talk to your pro shop about the strong pieces you already throw so the new one doesn't land on top of them.

A two-shot way to tell if you picked right

A good heavy-oil look is the ball picking up in the midlane, staying on the arc you started, and rolling into the 5-pin. Corner pins that kick means it still has energy. A 5-pin that just sits there means it used itself up too soon.

If the Ghost V2 never comes back, you needed more surface or a duller ball. If the Combat is standing you up in the fourth frame, you needed the Gremlin’s length or the Ghost’s 3000 grit. If the Wicked Gremlin is already left of where you wanted to be on a fresh house shot, you needed to play deeper, or you needed a cleaner ball than any of these three.
