The poundage on the bow is measured at 28". If you draw shorter than 28", the poundage is going to be lighter. If you draw farther than 28", it'll be heavier.

The Impala is a good bow to start with I think.I had one years ago. It was my first bowfishing bow. When Istarted thinking about hunting with a recurve I bought aMartin Dreamcatcher. Martin makkes good bows too. And you can find a nice one in your price range.
