I figured I would start here and get some peoples opinion on vertical bows. I was looking at a Bear Crux, Bear Traxx, PSE Bow Madness and PSE Surge, I have not hunted with a vertical bow in 30 years and wanted to see what is the big difference using a single cam versus a dual cam. I see both, but have been out of the vertical market so long I don't know if one is better than the other. Any opinions or advice will be much appreciated. Thanks in advance.
