i've skied most of the skis mentioned in this thread, but none of them are comparable butterwise to the pontoons.  i demoed them for a day, and it was unbelievable how easy it was to butter with the rocker. but you couldn't ski them for park, so i would recommend the invaders, my friend isn't a fan of his butterliscious's (sp?) and my 3 friends who have invaders like them a lot.
