Their version did not use the shoot through cables, which I feel was the major downfall to the design. It put too much stress on the limbs to work properly with a rod and slide design and torqued the limb hinges causing failures and limb twisting.
I'd heard that gripe from several people, and that was enough to keep me from ever trying one. The design has always intrigued me though. This is a version I'd like to get my hands onand test out.
