Hi, i have 2006 Martin saber with 60# limb and Dyna cam. i'm happy shooting with this bow. But now, i was thinking about to replace my 60# limb with 70# and at the same time replace my Dyna cam with M-Pro cam, what you guys think? . My string and cable is still in very good condition, and i dont want to spend more money to get another set of string and cable. So, my question is, can i use the same set of string and cable? hopefully they have the same length. please guys help me. thanks!
