The Radical Guru Master lives up to its name by being a master of total hook in oil. The core and cover combo on this Radical bowling ball offer a strong hook motion with unbelievable continuation at the backend and on through the pins.
This brings hook (currently) to the next level. This by for the biggest hooking ball out there, for now. Compared to the previous two Guru releases, this ball is earlier and a little bit smoother. The extremely drilling versatile core offers a wide range of drilling options benefiting every type of bowler. I personally have been using the continuous and low flare layouts with lots of success. 60/3.75/30, 80/2.5/45 and 100/1.25/60. Lots of hook and EXTREME hit, smoother and less hook with strong hit and super smooth and straight hook with big hit.
This ball is fantastic on high volume conditions. While this is the primary feature of the ball, I found that I also have the ability to utilize one of the low flare drillings should I decide to drill a second one. This is a nice option for the situation where you would like to ball down, but really like what you are throwing.

When I first got this ball I wanted to max it out; something to compliment my Thug Unruly (50 by 3.5 by 30) on the seriously long and heavy volume patterns. Also I wanted it to be a bit stronger than my Original Guru (45 by 4.5 by 45). I threw the Master on a house shot just for kicks and it was way too much ball for my rev rate, especially considering my house shot plays on the medium to medium-dry side. However, I wanted to give an honest comparison. Compared to the original Guru, the Master is about 3 boards stronger overall. I contribute most of this difference to the difference in layout. With the same layout, I believe the Master will be about a 1 board stronger overall in the midlane. One difference between the original and the Master is in the time in which the ball begins to laneshine. While my original had a tendency to shine up pretty quickly (thus requiring more routine maintenance to keep the cover fresh and close to box finish), I have not seen that with the Master. On the new 47' Scorpion pattern, I found success with the Master playing about 12 at the laydown out to 8-9 on the fresh. Despite the strong cover and what I consider a rather early layout for me, the Master gave me a surprising amount of downlane pop. As soon as the heads start to burn up, I have no choice but to put this ball away. It's just simply too strong in my hands without a good deal of oil in the heads. If you are looking for a ball that will absolutely hook on anything, the new Guru Master should be the only ball for your consideration.
Looking for more hook. Well check out this ball. It hooks 6 and 2 more boards than the black Guru.
It has the same core as the black Guru. But with a stronger cover. It has the same versatility as the black Guru. I have used it on long, medium and short sport patterns. It works well on all 3 different patterns. Another great ball from Radical Bowling Technologies. WowThatsRadical!

I was very impressed when the Guru Master .was released and drilled one up. This is a Heavy oil ball. If you are looking for hook on hevy oil this is the ball. The Guru Master for me is 7 and 2 more for me than the Mighty and Original Guru.
It was way too strong on the house shot in my home center. I tried it on a heavier volume 47 foot pattern and the ball recovered without a problem from deep inside line.
If you are a low rev player this ball is perfect for you. It will let younopen your angles up and still trust the balls recovery. If you do not have one yet I would strongly suggest adding it to your arsenal.

Since the Guru Master is such a strong ball, I wanted to try something a little different with the layout. I went with one of the lower flaring layouts (90 x 2 1/4 x 45) so that I would be able to use it on a wider range of conditions. Even with the lower flare layout, this ball is still very strong. At the box surface of 500/1500, it was too strong for our house shot. Tried various surface combinations and settled on 500/3000. The Master does a great job of blending the lanes and is a monster on the fresh. Thanks to the lower flaring layout, I am able to stay with the Master much longer than expected for a strong ball. Carry has been exceptional and the cover holds its surface better than any ball I have ever used. If you are looking for a strong ball for heavy oil, there is no better option.
I am very happy with it
