I'm a Sissy at the Bar.

I always wondered why those chopper dudes use 1/2" rods to make fender struts or sissybars...so my weak stuts died and I'm trying to make a new sissybar/fenderstruts of a 10mm Gamma bar for Euro 7,00 or so. First attempt is round above the taillight, Second attempt later with a square top following the taillight. Lets see whats nicer.
