I am interested in buying a 600. I was wondering if you could tell me the difference between a pro x 600 and a edge x 600. I know the graphics are different but what is the main differences. Which one would be better for jumping and aggressive driving? Also why does it seem that the edge x's are cheaper in price? Thanks.

The edge x and prox chassis are totally different, Prox is much better imo. The edge x is basically just a normal edge with x's plastered all over it.
The prox handles way better in the woods and bumps. If you ever rode the two back to back its really noticable.

Any other opinions on these sleds?

if you are into riding smooth groomed trail stick with the edge... if you want to bash big bumps and take the thing over the edge (no pun intended) get the pro-x... everything about it is stronger, lighter, more agile, and more race ready than any Edge sled ever has been...

The biggest difference is the bar set up. The pro-x is made to be standing up alot where as the edge is made to be sitting most of the time. if your big on groomed trails stick with the edge. The suspension is a big difference oviously too; edge is made for trails and pro-x is made for mogals. My buddy is big on just flying down the trails and he cant stand his pro-x 600 stock. I think is setup is way off but he went from a cooshy xlt trail sled that was a "cadillac" trail rocket.
