Jeff: I've used a wrist brace over the past few years due to medical necessity -- no brace, no bowling. So here are my thoughts:
You will experience a more consistent release. If you're a stroker/tweener by nature, you'll also probably see an increase in your revolutions. Because the brace locks you in to some degree, the ball is literally forced out of your hand, so you'll be surprised at the different roll.
But like most things in life, there is a trade off. The brace falls into the category of "be careful what you wish for -- it might come true". It will be more difficult to alter hand positions to combat different oil patterns. In this regard, you might have to make a ball switch where you would have previously just flattened out your hand. As a practical matter, the things get really sweaty in poorly ventilated centers, and that can be really annoying. And finally, you will lose some feel for a natural release. When I take my brace off to practice without it, I have little feel/control for where the ball is in my swing. I'm sure "feel" would come back over time, but the more you bowl and the longer you use it, the more dependent you become.
If you want to experiment, first try a Mongoose Equalizer. It's about the most comfortable brace available, and it's not too obtrusive. If that's not enough and you want to move up to something more restrictive that promotes more revolutions, consider the Robbys Revs II. It's a solid adjustable, but it's light, leaves free movement in the fingers, and very durable.
Let me know what you decide to do.
