Del hit the nail on the head. I think the whole idea of a shorter lower limb was "under-thunk."
They used to talk about getting the arrow pass at or near center by having the lower limb shorter. Then they said the lower limb had to be stiffer so it would return at the same speed as the upper. But a shorter limb will return faster without being stiffer.
This is one area where I think the archers of the ELB hey day stopped thinking too soon. No advantage to a shorter lower limb.
