Some of us apparently need to retest the theory from time to time. So far my personal data has been 100% consistent: hurts every damn time I do it! I have found that RHW, and LHW reels are equally effective, and painful, at busting knuckles. Why I keep needing to retest that is one of life’s great mysteriesOnly ever rapped my knuckles once on a hot fish, and then never again because ouch-learning works. Knuckle busters can happen with a right-hand hovering close to the handle too.
