Nothing wrong with tails! My kids love chasing them. And when I was on holiday the only question I was asked by a couple of people was "how come you don't have a tail on it today? It looks a lot better with the tail on" So rather than changing kites I just put a long tail on the DS ( should I be shot for that?) And the result was lots more people watching.
Didn't do a lot for my learning how to do tricks though, but I can do that on my local field where people are few and far between.
