I used the Pure Physics on several lane conditions as several centers and just could not get the reaction I was looking for. I have a Burst which suits my style very well. I throw 16-17MPH with a lower rev rate and found this balll would roll out quite a bit once getting to the deck. The Burst I have continues through the pocket and hits hard - this ball did not. I even had it redrilled so it would be more aggressive and it still did not produce the results I was looking for. I average 207 in one league with it and 212 in another league with the Pure Physics, but left a lot of 8-10's which is very frustrating if not impossible to pick up. Average around 220 with the Burst. Have not had that problem with the Burst and have decided to order an OutBurst for oily lane conditions. For me, it seems this ball may be meant for people with a higher rev rate. I'm thinking I have so much better success with the Burst that the OutBurst is a good choice. I use a 15lbs Burst and I'm going with a 16lbs OutBurst, so the speed will be a little slower and I'll get more hook, which is what I need on oily lanes. Just need a good dry lane - 10pin ball now. I'm thinking a Scout is the way to go - gotta stick with a Columbia ball...
Great for medium to heavy oil! I really like my Pure Physics and would definitely recommend it to anyone.
