Jason,
Again excellent videos for comparison purposes which is what videos are all about.
Doug,
Be careful about saying which is stronger when. Remember he scuffed the Diva with a 4000 pad, which, I believe, made its surface equivalent to the Brawler's Rough Buff Surface. If he left the Diva stock, he would have stood deeper and possibly it might not have finished as strong due to (his own words extreme carrydown!! I'd suggest if he didn't have extreme carrydown AND had left the surface stock, the Diva might have appeared to have more backend than the Brawler. So it, in many people's eyes would have appeared to be the stronger ball.
Keep in mind the Brawler is a solid/pearl combo, a hybrid and is ususally slightly smoother than the stock Diva. I personally don't believe it is a weaker ball, just different.
