I got my ION drums today at last and I was so nervous cause I live in Sweden and many have talked about problems with them and I can't just replace them if there was any problems but I can't find any problems yet. I have just played for maybe 30 min but they work great . I also got a roland kd8 from my mom for christmas (yeah a little in advance I know) and I have a real kick pedal so now I'm just waiting for the kickbox to arrive. The kickpedal is already modified for rb so I can use it anyways but It will be awesome together with the kd8. Btw the kickpedal that came with the drumrocker really sucks. It looks great but the sound it makes when you use it is terrible and the tension is just to light I think so I never connected it to the drumrocker.
It takes a while to get use to the new setup though and to know when to hit the cymbal and hihat but that only demands practice
