True, for most applications this is overkill. It can be useful for
large HLS where the large rubber results in a higher torque/axial
ratio. Then with the Boron & Tungsten for bending the poor shear
properties of Balsa are tested. Actually in that case, the wrap from
rear post to rear hook can be a big help. F1D55, no benefit. AROG
negative improvement.
