The third or fourth time I tried to tighten the speed lacing system on the right boot I heard a "snap." I was left with a broken, black lace held together by frayed, white nylon, or whatever the insides of those black laces are made of. I still gave it three stars 'cause it is as stiff as advertised. I like Burton's stuff, but I'm starting to question the durability. I've also got an '07-08 Custom X. I've used it twice, both times in Mammoth, CA over Thanksgiving weekend. Conditions weren't ideal, but I've got a small gouge in the fragile-looking topsheet on the heelside edge. There were some stray rocks jutting out of the thin snow base, so maybe it was my fault. It does make me wonder, though . . .
