Hi,
I'm relatively new to primitive archery, but in the last year I've come to shoot my self bows 3 finger with a half inch gap below my arrow nock. I've found this gives me a dead on point at 28 yards, but more importantly I can keep all my shots at shorter distances on target by aiming no more than 12" or so below the target. Whenever I try straight 3 under I have a much higher trajectory. Maybe I'm just not doing traditional 3 under properly, but leaving a half inch gap works well for me. I'm open to ideas.
As to this stressing the lower limb more, would adding an extra inch of length to the lower limb help distribute that stress better?
