If the savings between the 10 and 12 are not an issue, pick the one you like the best, based on style and color. Personally I held out for the 2012 model after wrecking my 1500, and likely would have gone back to the 15 if not for the new styling changes. I have no basis to compare the 2 bikes performance wise, but I can tell you I like the styling better, including the lighting front and rear, the new saddlebags and layered look of the fairing. I had a Corbin saddle on the 15 and loved it, but find the stock seat on my 12 very comfortable. Purchased 6/11 for MSRP with $750 in accessories, as of tonight, 10,450mi. I'm liking it more and more everyday! Good luck with your decision.
