When it comes to friction shifting a fd with 7900 dt shifters I actually prefer to use an older fd. The 10 speed units are narrower and require more trimming. For sti shifters there is a reason for that. For dt shifters I just try whatever old fd I have laying around that somewhat matches the group. 7, 8, 9 speed preferred.
