Dont really worrie about axle to axle length or ibo speed. If you want to get a good starting point for draw length to get you started get your wife or son to measure you. Hold your arms out streight and get them to measure you from fingure tip to fingure tip then take that number and divide it by 2.5 (if you measure 70" then you are a 28" draw length). Like I said its just a good starting point. Since you are new to archery I would start out with a bow that has a range from 50-60 lbs draw weight. Are you left handed or right handed. I have 2 bows here for sale one is a righty and one is a lefty. I have a golden eagle that has a 30" draw length but will need strings and I also have a Bear instinct that is 29" draw length with 60-70LB limbs. the golden eagle is right handed and the instinct is lefty
