You can likely get it down there safely. Turn the limbs out three full turns and see what you have got. The only thing is bows are more effecient with the limbs burried. You would get more speed from a 60lb model closer to burried than a seventy backed way down for sure. You may pick up some noise backing them way down. There might be some other issues too. You may be able to trade someone for a set of 60lb limbs on this site and it would be a better overall setup.
