Progressive 412's have worked well for me in the past for the price, but never rode them on an XS. I have perfectly good pull-offs from a Shadow 1100 that I'm going to get my ass into the attic and measure someday!
From what I've read here (I'm sure you have too) Calling 650 Central and having MMM go over your size, bike, and riding style and make a recommendation is the hot ticket.
