Does anyone have experience with both of these skis?? I've seen many great reports on the PX 301 on this site. I know the SPX is the new style, with the more aggressive deeper keel and stepped bottoms(like the performance boats). I'm looking for a ski that'll do just about everything well, trail ride, break trail, a little powder, and running the lakes. Primary riding is on the trail though. More steering effort really doesn't bother me that much having come off a 1000 Thundercat with 240 studs and 10" carbides. If cost isn't a factor, which one should I go with. And, I just installed 162 1.375 studs down the middle. Thanks for the help!!!
