I don't have one, but I've heard others complain about the negative degree,and wish they would've gone with the 0. The complaint was it put their wrists at a bad angle.
Looks like down angle to me. I don't see a point in getting 0 degree. You could invert a 1" bar and get the same feel. -7 degree is the way to go IMO. They look great and feel great.
Here they are side by side, you can only really tell by the inner section of the bar where you can see a slight down angle on the mounts, and the lettering on the bottom of the pics .
i have the -7degree. the rock, only wish they didn't have the extra inch on either side. as far as wrists, only awkward for the first week or two and only when sitting straight up. you get used to them and won't notice anything weird.
i was thinkin the 7 degrees would be more like a bolt's, am i wrong? thats just the way i was leaning like dave. and extreme and buellchick, did you powder those? cuz that was a plan of mine too.
