I have one and so far love it, I am running the 2011 fox talas 36's on it with 160 to 120mm travel adjust and an RP23 shock. I only swap out to 120mm when its so steep I cant keep the front end down. For more moderate climbs I leave it at 160mm as it feels more natural at this setting, the geometry suits 150-160mm even for long steady climbs. Its worth mentioning though that I run with no spacers on the headset so the front is a little lower.
Pedalhead, I had that creak as well in lower pivot I serviced all the pivots and it seems ok now. I think when it was shipped the pivots were not done up very tight and there was no loctite so they worked loose and caused the back end to have some play. What was the problem with yours? I also had to replce the DU shock bushing after 3 months due to the above I think.
One thing to bear in mind if you buy one is do some work on protecting the frame mine has had a bit of a kicking around the chainstay lower pivot… breaks your heart 😀
