I just had a CXP33/Ultegra 10 sp hub restrung to a Ultegra 11sp hub at PC&F. Seems to be pretty solid so far. Less than $100 for spokes (36H) plus labor. I did get the hub off ebay and handed it to them, so less than $100 to restring the rim to the new hub and new spokes. Not really even sure who did it there but they have always treated me well so thought I'd give them a shot. Good so far.....
