I cut my Gen II, started with just the out side edge 1' in from the inside of the rolled edge up to the spindel, ( use 1" masking tape as a templet ) worked good. So then I cut it up to 3 " in front of the spindel, got even better. Then I went up to the point where the front outside edge starts to transition into the tip, YeHa! now this ski will carve, but it still would not let the front end sink enough on a down hill pow turn, so I cut off the entire inside edge of the ski up to the same point as the outside edge. Now the ski will sink and let you control the pitch of the turn, but you still have the wider tip to give you the lift you want. It also reduces the steering effort in deep snow when your going slow and trying to pick a tight line in the trees. I started this mod on my Rev 159 highmark extream. Then I did it on my friend's XP 154, It's a great mod and simmions should just build'em like this, The XP responded really well because the Gen II is just to aggresive for this sled. I'll try to get some pix up.
