What I remember about clutches is that there are basically two different types Diaphram and Borg & Beck. Diaphram has a bunch of small fingers that generally speaking allow for more holding power with less pedal effort. The B & B uses a three finger system which hold good but requires more pedal effort. I don't know if it matters with a hydraulic clutch or not but back in the old days of mechanical linkage it made a big difference. On either system to increase holding power they upped the spring pressure. Then to further complicate things they started using different materials on the discs. The more aggresive the holding power the harsher the engagement. So clutches are much like everything else a compromise. How much harsh engagement can you stand. I personally like centerforce clutches which use the diaphram system andalso use what they call a dual friction disc. Harsh material on one side not so harsh on the other. When you let out the clutch it's kinda grabby initially but then it's easy to feather from there. All my rigs that have clutches in them use this setup and they are all mechanical linkage. Don't know if this helped or just muddied the water but it's my 2 cents.
all input would be great.
