I probably will just wind up confusing someone, but here is MY perspective on the Hoyt vs. Darton systems - Hoyt's Cam & 1/2 is a hybrid dual cam and the Darton/Merlin system is a hybrid single cam. Both are cabled the EXACT same way. However, the cable track on the "idler" of the Hoyt is cam shaped, where as the same track on the Darton/Merlin cam is round. The string track on both systems matches the shape of the lower cam. IMHO, the ATA should classify hybrids into two categories, the hybrid-dual and the hybrid-single. That could end some confusion and perhaps provide a little 'incentive' for the two camps to outdo the other in terms of cam performance.
