The Distortion gimmicks will not regularly be available to purchase by themselves, as training is essential for properly using and performing the effect. However, we do plan to offer those who purchase Distortion the ability to purchase replacement gimmicks separately, as in time and with frequent use, the gimmicks (as with all things) may wear out and require replacement.
There's no way we'd make you guys buy the whole set again to replace it, so we plan to offer a really good deal to make sure you can easily get a replacement gimmick if need be. That said, with careful use (as described by Wayne in the DVD), they'll last you a long time.
Regarding the color-- we know that that is important to you guys, so we're going to try to offer the choice of back design color (red / blue) at the time of purchase.
