Mars squares the axis from the South Node side, the worn groove you charge from, so the inherited heat drives crosswise into the turn with no slack, and the strain keeps returning as a step you fight your way around. You reach for the old weapon by instinct, swinging at a familiar target so you never have to face the real turn. That is not weakness. The grind is tempering a steadier nerve in you. Inherited heat was never going to carry this advance. The structure goes up the day you stop charging the easy target and let the harder one stand.
