Over time I have dropped in draw weight several times. I went 78# to 65# to 55# to 53#. There were no problems adjusting to each of these weights. Also, I have been shooting 40# since last spring as a campaign to improve form. especially my release. It has felt a little mushy and took some getting used to. However, after a while, it feels good also. Injuries, as a basis for weight drop, may change the whole picture, and medical attention may be advisable. Overall, though I like my 53# bows and can still shoot them, so I will stay with them. If injury is not in the picture, an average guy should be able to move up 5 or so pounds with no problems. A couple of weeks of solid training will prepare those muscles adequately. Moving down in weight will require some training as well since light bows often feel too soft, which will take some getting used to. For me, it has taken more conscious effort to drop in weight. Odd, don't you think?
