I purchased this ball, Blueprint solid from Bowlingball.com and had it drilled with a dual angle drilling of 40x4x50 which put the ring finger in the pin. The first time I used the ball was in practice in broken down conditions and the ball did great but when using in league or newly oiled lanes the ball struggled to make the turn so I contacted the seller and they got back in touch with me quickly and gave me advice on changing cover stock first to a higher grit 4000 and that didn't work then down to 1000 and bingo all the difference in the world. I bowled league last night and had a great night and flirted with a 300 not to be 2 errant shots but I'll take 10 strikes a game and be a happy man. I am just so very pleased with this ball and with the service level of Bowlingball.com. I also ordered the PathogenX and the Curse but stayed with the Blueprint Solid last night but look forward to using them as well. In my opinion these balls Pyramid work as well as any ball that I have ever thrown and you sure can't beat the price.
