I don't like messing with the brace heights and it all depends on the materials and the shooting tendencies when when shooting at game. With wood, for me, a touch stiff covers my butt when shooting at deer and turkeys. Adrenalin makes things have a little more snap for me. But when I am using aluminum at a 3d target, I tend to have a softer release, thinking about those damn rings makes my shot softer more often than stronger. Shooting longbows, that side plate thickness will make more of a difference with certain dimensions,materials and spines than others, like doug fir, for me.
