Hello!

I've been doing my research but thought I would ask the experts to verify a potential plan of action here...

I'm collecting parts for a 2 builds. Original plan is that they would both be 9 speed road bikes, the nicer bike using mostly Dura Ace 7700 parts and the winter bike using my old Ultegra 6500 parts. I've collected everything I need for the ultegra bike, but I still am shopping for 9 speed shifters, 9 speed cassette and chain for the Dura Ace bike. Since the nicer Dura Ace bike is my pride and joy and because 9 speed shifters are almost all used and expensive, it occurred to me that maybe I should do 10 speed Ultegra 6700 shifters with concealed cables, a 10 speed cassette and 10 speed chain...call it done.

One of my concerns is the braking. Will 10 speed Ultegra 6700 shifters pull 9 speed Dura Ace 7700 brakes OK? I think I've read that the pull is different but can it be adjusted to feel/work right?

Also, I love the look of the DA 7700 crankset. I want to use this crankset but how will it work with the 10 speed plan? I suspect it will be just fine but the Front Derailleur might need to be changed to 10 speed?

Thanks for any help you can offer. And here is a pic of some of the parts I've been working on:
