Hi dean!
Ive got 3 of these balls (2 big times and a XXXcel) and all are great balls. It all comes down to what you want the ball to do. Ive probably had more success with the XXXcel, having bowled 2 300's with it (once sanded and the other polished) on completely different patterns. It has always been a ball that has control, mine doesnt hook off the lane, but there is always a line to the pocket with it. You've already hurd what ive thought about the Big Time Pearl.
If your looking for something you can drill or resurface to use for any condition, go for the XXXcel, or if you want something that will take down any fresh condition, go the Big Time Pearl. Either way, your not goin to go wrong.
I hope ive helped you out a bit
