Leftside: After watching a video of you bowl, I'm surprised you ever felt a need to try a device. You have a natural 'cup and collapse' release, so a brace would only set you back. Whoever allowed you to put one on should be arrested for junior bowler endangerment.
As far as a device "doing a good part of the job for you", you're using the wrong mechanics if this is happening, and you're not getting the results you might think.
A device does not magically get you around the ball properly with the proper exit timing and follow through force. The comes directly from developing optimal release timing that is neither too early nor too late. With proper mechanics, the brace should do nothing more than assist with wrist stability that can't otherwise be achieved.
Along these lines, I once read an article (should have saved it) that described Pete Weber's experience with a Cobra when they hired him as a spokesman years ago. His comments were to the effect that "the device really didn't do anything to his release". And that's precisely the point. The brace should simply assist already well developed mechanics -- not attempt to 'create' them (because it can't).
I've seen legions of mediocre bowlers (i.e. poorly developed mechanics) put a brace on, get more revs because the ball is simply being forced off their hand with the same lousy techniques, and declare that the device has taken them to the next level. Self delusion is a wonderful thing, and many of these folks undoubtedly post here.
We are in agreement that a wrist device should only be worn for a good reason. However, I still maintain that to adequately evaluate the plus/minus of wrist brace usage, you have to have gone though all phases of developing your game bare wristed, then use various braces over the course of several years, and finally step back and evaluate without emotional baggage cost/benefit of usage one way or another. Hence my statement that you quoted.
