A 60# bow is fine. You weigh 120 pounds? That's fine... I almost got 100 pounds on you. I am 210 but I am 6' tall too. My brand new bow is a Reflex Highlander and I got it tweaked to 67# and 29" draw. The bow shop noticed me straining a bit with 70# but could easily pull 60#, so the guy tweaked it more and more until we both found a good spot to leave the bow set at.
