I've got them on my RTX and love them. The first year (last year) I just put them on in the center mount and let her rip. There was definitely an increase in steering effort. As in, your arms would be sore after a 5 mile stretch of twistys. However, this summer I had my suspension redone by Hygear and decided to try and dial this sled in, now that I wouldn't constantly be on bump patrol and could have some fun. What I found is that I can now turn the bars without the sled moving, couldn't do that before, and at the same time corner aggressively with very little to zero push. It's a combination of rear skid and ski setup. I've tried the rear mount hole and it further reduced steering effort but did add a slight amount of push, very predictable but it was there and I prefer to give an input and have the sled react. With that the conditions were loose fluff so take the previous comment with a grain of salt. I am not using the power steering plates but intend on trying them just because I have them. I'm currently using last years (worn) Stud boy shapers with 7.5" carbide. I think that the key to these skis is that you are not going to just bolt them on and go wow everything is better now. Everything is give and take, as with every other part of the sled. The point is that I now have a list of setups that works for certian conditions and I can relatively esaily change the setup to match the day. On heavy wet packed conditions I would go to the rear mount. On loose unpacked pow days I would go with center if not front. If I was going to be cruising rails or doing drags all day I would go stage 1 rear mount with easy steer plate; less drag and more forgiving. You get the point; I have not tried other skis, other than the stockers, so I may not have the best comparison of opinions. If you want to just bolt on a ski and ride, probably not the ski for you, if you want to be able to adjust for style and conditions and enjoy that aspect, I would give them a try. If I remember correctly at the Novi show last year they were cheaper than the Slydogs, with the mounts and all so pricing is not bad. Ultimately you can make them as aggressive as you can handle and then some, or make them forgiving and as loose as you want, well at least close. By the way the floatation is amazing, before I would sink like a stone (no surprise there) but now I've made it through pow three times deeper than I would have expected. They seem to disperse the extra front end weight very well. Now they're not going to turn your 121 or 136 into a Mtn, but you won't be afraid to blast off trail for the pow here and there.
Setup:
Skis.
7.5 Stud boy Shaper
Center Mount for all around riding, rear for heavy wet cond.
Stage 2 for all around, stage 1 for drag (which I don't do)
Rear skid. (Yes this does play a role in the ski setup)
Front limiter: Center Pos.
Transfer: 1 notch from Min.
Shock: Hygear, so it doesn't really translate
Front shocks:
Floats are at 65-75 PSI but again I have the rese's so 45-55 for non rese.
Sorry for the long post but I feel that skis (All of them) are like clutching were by you can't just bolt them on a go, you have to dial it in. The whole sled that is, you have to get them back to the peak RPM's for lack of a better analogy
