I have a 35" Encore II and 3 Challengers 37" as well as a Swampmaster 32" and my Daughter is shooting a Swapmaster 30". I shoot the P1 single cams on my 3-D rigs and have cam and a half on other bows. I have not shoot the double cam so I can not offer insight on this. But the OS-3 cam and a half is very hard shooting and good speed. 28" draw 60#'s 360 grain arrow shot 280FPS the other day on chronograph.
