releasing "last" clamp while tensioning "next" string. i've tried this (i'm on a lockout, eagnas 910 combo) and i have to say i DO see (watching closely) both (the last two) strings moving/pulling (in opposite directions). i'll add that when i've played with this i only do it near the end/lockout, not at the beginning of the tension/pull. seems maybe it could "reduce" drawback, producing a truer tension in the end. just a thought. your 2 cents?
