Roto Grip Perfect Gem Ball Review
The Cleaner Gem That Still Hits

The Roto Grip Perfect Gem is the most usable Gem in the line. It keeps the strong, early Gem roll bowlers already trust, gets through the heads a little cleaner than the original, and still drives through the pins once the pair starts to open up. Read the review to find out if this gem is perfect for you! Who should throw the Roto Grip Perfect Gem? Throw the Perfect Gem if you have moderate to high revs and need a strong ball that gets through the heads cleaner than the original Gem on medium-heavy to heavy oil. Skip it on a typical medium house shot, or if you're a two-hander on standard patterns.
