Mine are RC31, 440mm. Carbon legs, magnesium castings, about 800g. They're pretty stiff (haven't noticed any unpleasant flex or juddering). I'm using a 130mm stem with On-One Fleegle Pro bars and Superstar Excel lockon grips (quite thick), so any roughness from my unfashionable 2.1" tyres doesn't reach my hands.
My only experience of Pace stuff has been the second hand set of rc41 fighters as mentioned previously in this thread. TLDR, they leaked oil like you'd have thought only a sieve could!
RC41 is a sus model, I believe Magura bought Pace's sus designs. http://www.bikeradar.com/gear/category/components/forks-suspension/product/review-pace-rc41-xcam-10172/
