thats the kind of feature thats cool and all, and sure it CAN work, whether or not people make it work is usually the issue.
a decent feature with a decent setup usually rides pretty crappy. a decent feature with an excellent setup can ride awesome.
take the double barrel we had last year for example. that rail is incredibly well built and is just an all around great feature. but the lip sucked.
and the DFD urban setup, again GREAT rail but had a horrible lip. it was too skinny.
