I am looking to get a new bow very soon. I am shooting an older powertec thats a 60-70 lb bow. Right now its set up to shoot 62#. My question, am I better off getting a 50-60 or 60-70. I dont think I'll ever shoot over the 62# im at right now. What would my pros and cons list look like for both?

I would suggest getting the 50-60lb version. The reason being is that from what I have read a bow will perform best when it is at it's peak draw weight. Although the advantage to the 60-70lb version would give you the option to crank it up in the future.
