I agree that it's awfully difficult to stay awake through the first minute or two of that video- he'd probably make a great hypnotist.
I only have about 3 or so games in with the one ball I've had done, and I'm happy with the results so far. I stuck with the ball longer than I should have in league, resulting in probably the worst game I've shot in a couple of years, so I'm curious what the right ball for the condition would have let me do.
I feel like I get a little higher rev rate with no added effort, which may not be of much benefit to me, as I do fine in that area as it is. It does balance the ball in my hand a little differently, as more of the weight feels like it's on the pad below my index finger, where it's always been balanced between my middle and ring fingers. As long as I don't try to do too much to the ball, as I think I did the game where I should have put the ball away, the ball comes off my hand even cleaner than usual.
Jeff Richgels blogged about it a few months ago, and he said it helped alleviate a lot of the pain he experiences when he bowls. He tells the story about breaking his wrist as a kid, and not having it treated for a week. OUCH. The doctor said in order for it to heal properly, they would have to re-break it and set it correctly. Well, that sounded really painful, so he chose not to go that route, and regrets it to this day, as bowling has caused him quite a bit of pain ever since. He gives a really nice review of his experience with a couple of balls drilled this way, and promised a follow-up blog entry on the subject, but I never went to look to see if he has written that follow-up.
I don't have any serious wrist or hand issues, so I'm not looking for that magic remedy for arthritis or carpal tunnel, but one thing that I was told by the first guy in my area who started to drill stuff this way (Gary Faulkner at BowlersEdge Pro Shop
in Norfolk Va- he's done a few Storm ball reviews- look for him on YouTube) that he hits his target more often with this fit. It helps prevent you from turning your elbow and hand towards the inside, so you don't pull shots inside. He's got probably the smoothest game I've ever seen anyway, so anything that helps make him better is just scary for everyone else around here. He wins just about every sport shot scratch tournament around here, and has a couple of regional titles. Joe, he made match play at the Masters when you were there.
Right now I'm still kind of in the "a little knowledge is a dangerous thing" stage with this, so I recommend doing a lot of your own research on this- I don't suggest going out and spending $200 on Bill's video until you are comfortable with this, but if you do, I think you'll be able to recoup your cost within the first couple of weeks, as you will be able to sell this on new drillings and re-drills.
If you look at the ball I had done next to one that hasn't, you won't be able to tell the difference unless you look really close. Yes, the pitches are slightly different (Bill recommends a starting point for pitches that kind of over-standardizes them in my opinion- I'm using the same basic pitches in my fingers, just rotated slightly), and the grips now face about 1/2" left of my thumb hole. If you take the slug out of my switch grip sleeve, you'll now see the notches, which would line up with the bridge on my old stuff, now line up just outside my middle finger. It's a subtle change, and if your equipment fits you well now, you may not notice much until you get the ball into your swing and throw a few shots. I felt a difference when I would switch back to my old equipment, but only that I felt like I had to focus on keeping my hand behind the ball a little more, whereas it kind of just stayed there when I threw the tri-grip ball.
I think I'm going to get one or two more done this way, and report back on my experience. Just having one like this doesn't let me change to something else when the lanes start to break down.
