I have the
SID XX 120. I don't like the XX damper. Listen to Seksy. You loose comp adjustment and only end up with a combined floodgate/comp adjustment which sucks. I have replaced my XX damper with a
RLT damper which offers more adjustment and in my opinion performs better. RCT3 damper again is dumbed down for dudes that can't work an adjuster. If you can get a SID 120 RLT go for it. It should be cheaper than the XX. By yourself a
poploc adjust and you get remote lockout as well as remote compression adjustment. Why they no longer do a fork with poploc adjust is beyond me (but the solo air crap is also beyond me).
