Ultegra 8050 or 6870?
Just wondering if anyone else out there is considering Ultegra di2 right now and if so which way would you go? There seems to be some good deals on the 6870 stuff right now and one could save about $250-$300 bucks by not going with the new 8050 group. Other than possibly being a bit better looking and the rear derailleur having shadow technology, what would justify spending the extra cash? I thought about just getting the 8000 crank and using the 6870 derailleurs but it seems Shimano has moved the chainline enough to where the older 6770/6870/9170 front derailleurs won't work with the new spacing and who knows at this point if you can mix and match any of the new stuff with the old stuff? Any thoughts?
