If I could do it all over again, I would get the 60 pound bow, crank it all the way up and install the speed/fast cams. Yes you will be happy with the 60 pound bow. The 70 pound bow I have has 5 pounds more than I need or can use. I have to keep my bow down to keep me in the .340 spine range. Any higher with my bow and it forces me into the next spine which requires a very heavy 520+ grain arrow. So basically I'm not using the top power of this bow. 60 pound bow with fast cams would have been more than enough.
