I usually go above, going against what the teachers at Burnley ( Uni of Melb) taught us which was to always go below.
I only once ever seen the rigging point go and that was on a poplar and we knew it was probably going to go and didn't care as no damage could have done as the shed below was being demolished anyway, ( plus we were all in a silly mood), so I would say above except for snappy species willows, poplars Kauri pines etc.
