Jpx...
There was a mod on here some time ago and that was his ski, the HX. I don't think he would own anything else.
Usually, the sport models (especially older models) took a bit more experience to handle, since they were light weight and powerful. They don't like ridin two people easily. The buoyancy isn't as steady as say, the GTX or GTI models. Even the XP is a bit more stable. But, he (JPX) said that thing rode like a banshee......
