I am getting a Spyder Turbo that will be here tomorrow. It has the #3 Cams on it, the one I shot had the #2 cams on it and I loved it. My question is how much of a difference is there between the two cams, feel and speed? Is it still a true 28in draw with the #3 Cams?? And also how much would it be two have to buy (or could I swap) the #2 Cams strings and cables???
