Familiarity: I've put it through the wringer
Ready to dance down whatever you put in front of it, the HDR 650B is quite the quiver killer. If you're riding a ton of park or hard DH, you may be more apt to stick with the 160mm travel/26" version, but I love the subtle improvements that the 27.5" wheels bring about, and haven't been feeling any lack of oomph for suspension.
Really, the only complaints you hear tend be be on internet forums (cough mtbr cough) are that 1) there isn't enough travel and 2) rear tire clearance. To that, I think a 140mm front fork (34mm ideally) mates really well with the 130mm rear, and while it's not ideal for hucking off your roof to flat, it is completely at home getting bashed down the gnar in your local (or EWS) race. The DW-Link pedals (and climbs) wonderfully while providing really active squish in the rough spots, and it ends up feeling like more than 130mm. (That's what she said...)
I'm running a Hans Dampf 2.25 rear and think it's a nice match for my "enduro" build, and haven't had any problems with tire clearance.
Consult the reviews here + the rest of the internet/magazines...but if you can, get out and demo an Ibis. You'll be psyched, and compared to similar products, your wallet will be pleased with your purchase.
