A buddy gave me a set of 31 inch draw revolution cams that I want to put on a 30 inch draw bow. He has a set of 30 inch draw cams on his bow and He shoots 28 inch draw PSE Baby G. When He bought the bow, no matter what he did he couldnt get 280fps out of the bow and now it will shoot 311fps all day long. Has any one had any experence with the switch over with these cams? If you had will you please tell me about it. Thanks
