I think straightarrow makes a very good point with regard to bow hunting bows. Single cam bows appear to be more simplistic than dual cams and advertising has gained much public appeal for the single cam. There are quite a few bow companies that do not have twin cam bows as part of their current line-up. Are there many bow companies that only offer dual cam bows? It's a wash for me. These guys have really piqued my interest in Merlin bows and Pinwheel's explanation of the benefits of the dual cam have certainly made them more appealing.
