I would go with 50-60, but the final decision is yours. It's what you are comfortable with that counts. If you can comfortably handle a 70 pound bow, then go with it if you want. But don't let your testosterone override your brain when you make the choice. It's archery, not strongman competition. Like bigcountry said, the things they've done with bow design in the past few years have 60 pounders doing things almost as good as 70's.

I shoot a 50-60 Hoyt ProTec. It gives me the exact same performance as my old ProVantage did at 80 pounds 20 years ago.
