I still recommend a Sinister. It hooks as much or more than most of the other heavy oil balls on the market, plus you get a stronger more definitive movement on the backend with continuation and hit. We've all had several discussions about bowling ball technology and where it's going or not going, but the Sinister still stands out to me as perhaps THE best heavy oil ball on the market right now. We'll have to see what Motiv's Jackal and Storm's Crux does, but for now, the Sinister outhooks the Mastermind, Zero Gravity, Hyper Cell, Ruckus Feud, etc., with a better transition on the backend, better energy retention, and better continuation. I have to say I've also NEVER seen a ball that hooks this much that plays this well from extreme angles. I was playing 5th arrow the other night pitching it to the 5 board (house shot, just playing with it), and it was finishing driving through the 8 pin. Been a long time since I was this impressed with a ball.
That aside, I still agree with what several of the recent posters have said.
