Seats looks really comfortable. While I think double harnesses are great for personal protection I have heard comments that they were pretty restrictive when it came to general trail riding. In general because they don't have the self retracting roller at the attachment point. Do these have it or is it a fixed mount?
If it's fixed are you going to put in a secondary belt system?
Center grab bar: Nice idea. I assume you'll move the radio back further as I remember it being up close to the windshield. Or was it farther back than I remember?
You going to wait till you scratch the tubes before you paint them black?
