I think optimizing the RTP is the ideal scenario. I don't think there is going to be any performance or safety advantage with the R-Style. All of the elite level guys use a RTP. Like Horton was saying the R-Style is kind of a tweener for guys leaving the double boot system, but don't feel comfortable enough going to the RTP.
The basic rubber overlay for the RTP seems to be the preference over something adjustable.
One difference you might notice is the height of the RTP footbed. Some of the guys use no footbed at all with only grip tape on the plate. The Wileys is pretty thin too, and then the HO has some padding, with the D3 and Connelly being a bit thicker. I have never used the Radar RTP, but looks similar in height to HO. That rear footbed height has a pretty significant impact on the attitude of your ski and how quickly/easily you can engage the front of the ski into the pre-turns.
