When you get past all the advertising hype, myth and misconceptions, I think the biggest difference between solo' s and duals is that the single cam is quieter. You get the speed of a hard dual cam with the quietness of a round wheel bow.
I still like duals better though.
My thoughts exactly! Well , sort of. I' ve shot solo cams that were just as loud or louder than most dual cams. But the majority of them are quieter.
I prefer duallys myself!
