looks interesting indeed, but I'm unsure about the flat construction, sure they're up high due to the "your ad here" centerbrace and crossbar pad but I still think it'd feel weird :silly:
I think they'd feel fine if you wanted to drastically change your bar position and height, but I just question the strength of the clamp section of the kit.
I saw those at my local shop. They look very burly!! Looks like they would be very strong bars. You would have a heck of a time trying to mount an enduro comp. or stabalizer though.
