Djembe_G -- you are right, the Kelani Flex Drums do not sound particularly good (esp. compared to the Toca Lightweights). I bought two Flexes to use w/HealthRhythms groups just to try them out, but don't like the sound. The heads also do not come on and off easily at all. I do want to check out the Versa drums instead, for their nesting value. I'm sure they will sound infinitely better, too.
