I was looking at this too. I like the looks of the aerial freeride. I have no facts to base this on. just looks. but with the Canadian dollar so bad, I am not buying one of these any time soon. I was trying to find a picture of the oem tower for the challenger 2000 but wasn't even able to find one. but I found a bunch for the x20. I really like the way the horizontal curved bar matches the grab rail on the boat. really makes it look like it is purpose built.
anyway, you find anything you like?
