If you are going to stay at that draw weight 500's should be fine, however I just went through this for my Dad and I went with 400's. They are a little stiff but going to a heavier BH will weaken them up some, there is kind of a fine line at that draw length and weight between the 2.The 400's also give you the option to go to more draw weight and still be in as far as the Easton chart goes. These are only suggestions and there are lots of different ways to look at it but I'd rather be on the stiff side spine wise and be able to weaken it than be on the weak side to start with.
