Nice vid, lol very year 2000 of you with the music. If you wouldn't mind a suggestion, your ball roll could be tons better if you let go just a tad earlier. On balls that aren't strikes (doubt there are many of them) I'll bet it's not overhook or misses left, I'll bet you leave soft or ring 10's or the ball hits the spot and just doesn't check up strong enough. Letting go earlier would get your track further away from your thumb and make it stronger overall, eliminating the only issue you look to have. Again, nice video.
