I have a set of early DT Swiss XMC 130’s that basically have the RC41XCAM internals in a better made set of externals (the seals in particular seem a lot better than older Pace stuff). They have been great in the year I have been using them – a real step up in stiffness and bump capability from the RC39’s I used before. No issues so far.
I also have or had 3 sets of RC39 (85mm, 100mm, and 100mmm C-type), and two lots of RC36’s (an Evo and EvoIII I think). All have worked flawlessly except the RC39’s weeping plenty of oil around the seals, and their lockout sometimes refusing to lock. The feel and the weight of Pace forks are excellent, and in my case the worst “mechanical” has been having to adjust the lockout…
Pace get a thumbs-up from me!
