About ready to push the button, but I can't really decide between the Dengfu M06 or the WCB-M-108 / LCFS902 / CS-821.

So i really need your help and advice

My goal is to build a fully capable XC racer as aggressive and light as possible. I'll be mounting it with my Rockshow SID XX 100mm from my old hardtail and I'm planning on getting the Monarch XX rear damper to go with it in the back.

What should I go fore? What are the pros and cons to take into consideration when choosing between the two models?

Racing XC in Denmark doesn't require 120mm of travel, so nothing to gnarly

I'm coming from a Workswell 062 hardtail in medium (17,5") with a LOT of flex in the rear - too much for my taste when really pushing it in corners etc., so would really perfer a firmer ride.

 I'm 5ft 9in (176cm) and weigh 160 punds (73 kg)
