wow, the RP23 is really something else. but i bet that would really be expensive. i am ok with the float R that came with my frame.
btw (medyo OT), i saw an ellsworth frame (ephipany ata) coming with the same float R, and not an RP3. (the guys at the store, were even joking about it not having RP3 at that price) but i guess their ICT design is top notch enough. but there are models now with RP3s, and definitely we'll have models with RP23s.
