Let me preface my question with the facts that I am new to this forum and I've only been shooting a couple of years. I recently purchased a vipertec with 50-60# draw. With my other bow I was pulling between 58-63#. With my vipertec I can only get exactly 60# from it. I find the draw easier with the vipertec and would like to increase draw weight. Will that entail changing the limbs and cam module? If that is the case how expensive will it be? I know I should have bought the 60-70# bow but I didn't think the draw was going to be that easy and that my muscles would develop that fast. Thanks for any responses.
