Your clutch technique would put the lever in the same spot in relation to the fingers you are using that I had it in. When you move the perch in, as in closer to the middle of the handlebar, you would in return move the lever in towards the center, bringing the bend in the lever closer to where your lead finger would pull at that spot. (Does that make any sense?) The thing is, if you are using your middle and ring fingers, then moving the lever will make no difference. I moved it in because I use my index and middle fingers on the lever. I never noticed a problem with the shorties because my ring and pinkie fingers stay on the handlebars. As such, I would not know if there is enough room for all four fingers on the lever. You could probably fix the problem with a longer lever, or keep your pinkie finger on the grip.
Clear as mud?
