Big John,
I'm not suggesting that other systems don't work...Yes perfect scores have been shot with these other cams, it has also been done with prong type rests and other equipment from the past. But archery has evolved and when the "moment of truth" arrives, would you not want every advantage possible? Also, We as archers can get used to, or tune our bows to whatever conditions we "need" to to compensate for deficiencies that exist in the then, current technology.

Rangeball,
The avalanche extreme is about the same length ATA as the Q2 and I want a more compact bow for ground/still hunting situations. If I were making a lateral move I would definitely give this bow a closer look. However after shooting the magnum that avalanche would really have to shine bright!
