Uhhh....yeah, what Jeff said.
I am currently shooting two single cam bows at the moment but was also shooting two hybrid cam bows earlier in the year. To the surprise of many I prefer the draw cycle of the single cam design both in terms of the prolonged plateau at peak weight, the relatively short valley and the extremely solid backwall.
Plus, I am a hunter...plain and simple. I look for a bow that is accurate, quiet, easy to maintain and fun to shoot overall. Most of the single cam bows I have owned/shot in the last few years fit this list of criteria quite nicely.
I consider myself open-minded enough to always try new designs. The cam system is only just one part of the bow. The rest of the "package" needs to compliment the eccentric design and vice versa.
