Juro et al,
IMHO tight loops have nothing to do with a short speed up and stop. If the vector of a long stroke is consistent, back and forward with an abrupt stop, and...insuring the rod is slightly lowered with a thumb tuck on the forward stroke, a tight loop will be formed. This is not distance. Distance is a combination of a tight loop, and stored energy in the lever with an abrupt stop. Released stored energy can be maximized by a short speed up and haul before the stop.
Lefty is my hero, but I believe he addresses the beginning/intermediate caster in his techniques with some ideas for advanced casters. I think we are out of that box in our discussions.
