Was thinking maybe if I throw an 8000 FD on there with it's short little body, maybe it'll be a quicker/snappier shift???
Wondered if anybody else did the same & noticed a difference. (Or DA or 105)
TIA
With 105, found that 5800 (long) was not compatible with 5700 (short), the cable pull is too different.
