Stig: I stood there in Lowes for about 10 minutes with glossy black and flat black in my hands, debating on which to get. I still may go back over the flat with the glossy, it might look good on the exhaust too. I have noticed that the flat on the grab rails does tend to attract finger prints, glossy should eliminate that. I'm a graphic designer so when I was deciding on seat cover color and what to paint the other parts I "tested" it all out in photoshop first. I ended up doing come crazy color schemes.
Mscmkr: When I had my seat made I asked for a matching pair of grip covers, they guy made them for free. It's just measured leather with shoe eyelets. I used some double sided duct tape to hold them tight. The way they're laced they don't quite meet in the middle, I plan on stretching it a bit and straight lacing them so they wrap all the way around. They do make the grip a little fatter but where the laces are it gives a good place for your fingers to grip.
