I mentioned it once early last season when somebody else asked. I'm running them ('05 Fusion I think?). They're extremely aggresive compared to the stockers with no other changes (ski swap only, prior to adjusting to compesate). I ended up taking a BUNCH of weight off the front end - but that could easily have something to do with what I have going on in back. There is no hint of pushing, ever, anymore. I can now slide the back of the sled around, kinda, a lot of the time. Before, trying to do that was hopeless. I would encourage you to try it if you have a pair laying around. The bumpers I used were from SlyDog - but I'll bet there's a better fit out there somewhere. Mine were a challenge, could still use a thicker shim in back I think? Coming up with a set of those will be the hard part. Please post if you find something!
This past season probably not the best example of prime conditions to try them out in, but I'm pretty sure there is nowhere near the amount of snow coming out from under the front of the skis that's blowing back over the top of the windshield either. These seem to have much better flotation/control up front. FWIW
