First off, at 5-7" I doubt you are anything over a 28 inch draw and maybe not even that.

You need a bow that is easy to carry and shoot accurately, something with an IBO speed rating around 300 fps, brace height around 7 inches and in the 60-70 lb range. Match this with a well made arrow that spines to the bow that gives you a final speed around 230 - 240 fps with a cut on contact 2 or 3 blade broadhead. Make sure its tuned PERFECT and you can group the BH very tight.

Then pick your shots carefully and you will have no problem!
