Hey Dean,
Firstly, it would be worth your money getting a Big Time Pearl. The ball is amazing, so amazing i had to get 2 of them. The ball seems to fit any lane condition, and hits like a train. I've had one for about 7-8 months now, and in that time, it has almost always been my bench mark ball, even being able to bowl a 300 (not to mention Shannon Miller also bowling a 300 with a Big Time Pearl around the same time) with it. People talk about having a ball that suits them in every way, and this would be my ball, i love them!
Im sure gavin will do a great job (as always) in setting you up with one, and you definately wont regret it.
If you wanna know anything else about it, feel free to pm me, cheers
