Looks great! I ordered the exact same configuration for my black Tbird and it should arrive tomorrow (Thursday). I really liked the idea that ordering a single backrest allows you to move it between rider and passenger - or leave it off altogether.
Can't wait to try it out - the stock seat is absolutely getting worse for me each time I go out, and I've heard too many mixed reviews on the Triumph long-haul seat. I have yet to see a complaint about the Corbin - other than pricing and their customer service. Here's hoping the latter won't be an issue for us.
