I believe my quest is over, I've determined the perfect screwdriver set doesn't actually exist.
Every set I've tried will have some handle sizes that I simply don't like or just find wrong for the particular screwdriver size.
Perhaps the 1/4" -5/16" are just right but the #2 is too small, maybe they're even too big or I can't even get certain drivers in a set.
The Stanley 100 plus set probably came the closest, but there's also no such thing as a perfect handle that's ideal for every grip / technique.
anyways these 9 drivers currently comprise my ideal general purpose screwdriver set.
Some Williams, some Tekton, Stanley 100 plus, and that awesome old Wood handle PROTO.
