When drilling this we were looking for something that would create more angle in the back of lane that could be used from inside angles on med to dry conditions.

Testing the Gemstone on a league shot it turned out to be stronger than expected. It was clean through the fronts but had more of a midlane read than we thought it would, making it a little smoother. Still a great bowling ball however. He was able to start deeper than the Hi-Road is was throwing, but as the night went on it became to strong and had to square up with his Hi-Road.

The most impressive thing I noticed about the Gemstone was how well it went through the pins. He was tripping out 10's that he was leaving before, and the dead flush ones he threw were devastating. The Gemstone seems as though it will match up well for a lot of different styles but will be more beneficial to tweeners. Lane #1 is really making some great balls as of late.

Got my gemstone drilled up tonight i had league i threw my rogue cell for league the last game had a hard time controlling it. it wanted to take off too early so after league was done. I had them turn on the same lanes we were bowling on so i knew they were burnt up. First ball i throw smashed the pocket the ball is awesome i threw one game with it only two balls didn't strike. I threw the same shot i was throwing with my rogue that wanted to take off to much but the gemstone just set up perfect i was really impressed. It setup the perfect one two combo i can't wait to throw in league. It goes long but the backend reaction and the midlane read is incredible.

About the Bowler

Ball does exactly what I wanted, hits great, carries well. Shot 289 second game out of the box. Need a ball for drier lanes this is it,had no success trying to score going out and in, to much work trying hold line. Almost effortless throwing Gemstone. Hit the seven board walks right in. Should have bought this ball in the beginning of the season instead of the Rogue cell

I got this ball for my 10 year old son....he was rolling a 12lb Black Widow Venom and I bumped him up to a 14 lb Gemstone....probably the best move we made for him...he went from averaging 150 to averaging 170 almost instantly....he has alot of hand and considered a cranker...he can make this ball talk....how ever he want to release it it will roll true...it has alot of forgiveness for the mistakes a 10 year old makes. he does have to keep the ball a little tighter line torward the center...if he rolls it outside the 8 it come back way to hard for his speed. I am thoroughly impressed with the quality and performance of this ball...I recommend it to any caliber bowler.....well worth the money spend

I recommended this ball for a friend of mine. He's a moderate cranker with higher ball speed. On a T.H.S. he tends to get an over-reaction with his more aggressive equipment. We got this baby drilled for a C.G. out Leverage and this produces a very controlable shot on med-dry conditions. Definitely another winner from Lane #1.
