Up grading your stock strings to after market will give a few fps, I also added speed balls on my 3d bow. Gave me 2 extra fps. But, you want to do this safty first. Make sure your arrows w/ bow weight is in the proper spine/deflection. Getting speed to reach out to 60yds isnt as important to getting out to 60 yds accurately. If your shooting at game its the human way to go. I can shoot awesome groups at 50yds. and am at aprox. 278 fps. I would worry more about shooting 60yds accurately. IMO!! Good luck!!!
