Went with the Shadseat after getting a very nice deal from them for the top case and the seat because they didn't have the gold trim available. The Corbin has fitting issues with the FZ8 and turned me off from them as well as the fact it changes the seating position to a more relaxed one, still want my sporty seat!
Love the mounting system for my bike from them, just replace the passenger seat with the mount and I can put whatever shad case I want on it, no big mounting brackets required.
Still haven't decided on windscreen, but looks like the Givi one is the one I'm going to go with.
Also went ahead and replaced the stock headlight with a projector kit for the trip as the high beams do nothing stock.
