OK. I went ahead and did the deal. They changed the crank and matched like for like with Ultegra SL for zero. To me its even better with the compact on there. Thanks for the replies and advice. I hope to hang out learn a lot and contribute when I can.
Now I need pedals.... I just put some Forte campus pedals on that I've had for a while. Feels like swearing in church with those heavy bits on there.
