It's all a preference. Pretty sure DBD runs clipless, but I could be wrong.

I used to until I begrudgingly had to get a new bike (I like it now though ) and plan to upgrade to DX's as soon as I have the money. One thing I learnt is that it gave me so much control over the back end especially in rocky sections or rockgardens in particular, along with the obvious pedalling benefits for sprinting. This was on a hardtail however, and personally I wouldn't think twice about it. See if you can borrow some for a test spin. Ever ran clipless on any other kind of bike before?
