I just bought the Shock Doctor today at my local Dick's Sporting Goods.
NO ONE should go buy one. It, um, well.....er.....OK, it's sweet.
I took it straight to my NAPA league night and only got a couple of shots in during 2 warm-up games, before having to go play with it for real. Yes, it felt weird. It felt constrictive. It took away some of the feel/touch that was mentioned above. But, I'll be damned if it doesn't keep your wrist straight as an arrow.
I had NO IDEA how much the wrist was the key to your game. Because I constantly kept feeling myself wanting to twist and turn my wrist, yet the Shock Doctor would have none of it. Consequently, my stroke was straight and I was pocketing everything except the occasional low percentage shot.
Actually, I say my stroke was straight. And technically it was. But, as I practiced lagging (lagger's choice session), just moments prior to my match....I noticed my CB was tracking pretty noticeably to the left. I quickly realized my body was in the way of my stroke and I had been hitting "across the CB". I made a subtle adjustment to my stance/body alignment and it ironed most of that out. But, it's food for thought when I can get back to the table.
I ended up beating a lower level player 5-1 in 8B, in what was a race to 4 for him. While he did make me work a bit, only a failed BIH attempt on a "small" side pocket....trying to solve a problem-ball....stood between me and a "Rackless" match. It was a feast or famine attempt, and I went hungry on it, while my opponent got out to taste his only score.
I got home, actually looked at the instructions, and realized that you can adjust/remove some bracing in it. So, now I can't wait to get to the practice table and see if I can get really comfy with this equipment.
Again, I don't need any more competition, so I implore you....do not buy this brace!
P.S. I'm a lefty, so I obviously bought one for that side. But, considering how well it works, I'm seriously thinking about picking up one for my right side, so I can practice off-handed. I'm fairly ambidextrous, but lean towards being a righty, in reverting but pool bad shooting a gun. It's too long of a story for here, but I see the table much more clearly from the right side....and have a nice stroke, but once every few shots or so, my right wrist will just do a crazy spasm-twist and I'll drive the OB into the rail.
I think the Shock Doctor would fix that. I'd LOVE to switch over to being a righty, as I think I could be a better player in the long run.
