I'm in the market for a new X19 or an X21 in the next couple of months and was hoping to get some opinions from those who may have knowledge of both. I'm currently in a 18.5' Triton aluminum and overall I'm happy with it--with the exception of speed and rough rides in choppy water. With that said, can anyone compare speed and the ride quality between the X19/X21? Unfortunately, I don't have an Xpress dealer in central NC to test them on my own so I have to trust what I read here before I drive to pick one up. Thanks!
