Second that. Have it as well and just starting to feel broken in. As far as changed position, just slightly forward and slightly lower. Looks are great as well.
I had the HD backrest on the stock setup, but it pushed me forward to much and after awhile with your sac smashed between you and the seat long rides aren't run anymore. The new seat and backrest doesn't present that problem anymore.
Mine pulled be 2in back and roughly 2" up necessitating I lower the rear and changing handlebars....comfort, took a couple thousand miles and I dont know if my *** broke in to the seat or the other way around but I prob shoulda sent it back after the first ride. Find it too ridiculous to have it modified by MCC after spending as much as I did for it..
