I ask because I am thinking of trying an 8050 rear derailleur with a 6870 front derailleur because the 8050 supports 34 tooth cassette while the 6870 only supports 32. I'm running a 36 tooth cassette right now. No problems shifting with the 6870 but I'd like to try it and see if there is a noticeable difference.
My concern is a mashup of 6870 and 8050. I"m not sure that firmware will allow it.
Do you have a long cage RD? With a long cage you could probably do a 34. My wife has as short cage but after talking to the bike mechanic guys I know, they say for many people they can get an 11/32 to work on the short cage with a compact crank. At that point your ratio is almost 1 to 1, 34 to 32. If you have a long cage RD, I'd try the 34. Tighten down the B screw but I suspect it will work.
