yes it is primarily for looks
Any way you can make kind of a catalog/display, either here or on your website, showing all the different bolt fluting styles/patterns with associated names or #s? Would make selection and ordering a lot easier rather than trying to e-mail or call and say "I want something like the design on the 4th from the left at the top of your picture".
aside from making a bolt look really really cool, what kind of weight savings are you getting, on average?
power corrupts, but absolute power is kinda cool!
honestly I have never weighed one before and after but I will next time and post
