What are the actual or supposed differences between single and dual cam bows? I haven't been able to find much objective information on the subject, save for a few forums. From what I've been able to gather, single-cams are a little smoother on the draw and maybe a bit quieter, while dual cams are a bit faster. But... I shoot a Hoyt Defiant single with 10 year old technology. It's smooth and quiet, for sure, and back in the day it was probably a screamer at 265 fps (that's me, not IBO). I've also shot a friend's Matthews Switchback and some Bowtechs at my local shop. I thought the Bowtech Allegiance was darn near as smooth to draw as mine and way better than the Switchback. It's also scary quiet. And at 320+ fps, it's plenty fast. So I'm left thinking that there aren't many, if any, inherent advantages to either style. What do you folks think?
