Anyone WCB-M-120 / CS-386 experience? 29-er XC hardtail (edited frame type)

[gj-070]

Hello,
Since my 036 rear swing arm broke i am orientating for a hardtail build as spare bike . Topic 036: http://chinertown.com/index.php/topic,904.0.html

Edit the subject, was: I was looking and found the CS-887 from Xmcarbonspeed interesting.
Searching on the web didnt give any experience hits to this CS-887, anyone here digged into this frame model?
Any frame damage experience so far known on this CS-887?
Any geometry / riding / handling experience with this frame?

I am looking for a race XC MTB, 29-er, 100mm fork, 2.1 tires, good handling in single tracks, good climbing, solid frame with no easy cracks.     

Last weekend i made a Excel geometry comparison with bikes i have ridden and some currently popular brand XC bikes.
The WCB-M-120 / CS-386 look like a geometry that i am looking for.
