Some opinions of that very Q here (you may have seen this already):

I got an XC just before Christmas and think it’s up to most / all Scottish trail centre stuff – probably not proper DH though. However those there Alps could be the fly in the ointment! No idea on the AM sorry.
It’s firmer feeling (or maybe that just the lack of bobbing) than the Commie Super 4 it replaces – and has no problems with jumps!
Is there anyone localish to you that has one and could let you have a shot at either?
I posted on here and stanfree did a swap with me for a couple of hours before I hit the buy button.
The other thing is if you buy one and dont like it Canyon do a 30 day money back no quibble thing. I’m not sure if you’d have to pay return postage though.
