Hello Marc,
She's wrapped as the result of a previous experience. My last warbow (about 140+Lb @32) had the same binding because the low bracing hight and timberhitch was bruising the belly side of the tips. The wood was the softer English yew. After about 200 shots the lower limb just below the nock snapped clean off. As this happened with a heavy war arrow, most of the energy was absorbed and I was able to fit a new nock and the bow survived. I partly attribute the clean shear to the binding, hence it has become something I practise.
Cheers,
Jeremy
