The EHP 190 is just the VCT 190 from last year, same ski (VCT is only shorter lengths now because Vinnie is short? heh). EHP 193 is a new ski that is wider, much stiffer (it is very stiff, nearly B-Squad from what I've seen). It also has no camber in part of the ski, can't remember where. It's made for going really fast in powder, straight/big turns without hooking up the edges.
