Limbs will be adjustable from 60-70 so that's not an issue if you get the 70lb limbs. Sky is the limit, Lots of close-outs this time of year on new bows that never got sold, trade-ins at bow shops, ebay, etc. Just get out and shoot and decide what features are important to you, what bows fit your hand well, etc, then work from there. Buying a loaded out used bow can save you hundreds over buying new. Good luck.
