First ride on the wedges....I don't see anything negative with them. I can hear the track clips on them on deceleration but otherwise the steering pressure seems uneffected. Not sure why anyone would think they would increase ski pressure without trying them first. I didn't find that to be the case at all, we rode everything frow groomed road to thigh deep, a lot of hills, gullies and tight technical trees.
As for how they work to get the sled "on top", that is something that is obviously very tough to measure. I have several rides in the deep on my sled and have a good feel for it. There were several occasions with the wedges that I though for sure I was going to be digging and it just kept going....slow, fairly steep through trees where you had to be in/out of the throttle and several other XP's and XM's did not make it even in the track. Maybe it was just luck on my part but I was VERY impressed with the combination of the XM and Toms wedges. The XM without them is impressive....the wedges I do believe give it a advantage in the conditions they are designed for...the concept makes sense, it was one of those "why didn't I think of that" things when I first saw them. They will be staying on my sled and I won't hesitate to send people to Toms for a set...we are not a Toms distributor at this time.
