RE: to big for a safty harness what should i do
Ditto what others have said. BUT, if you insist, you could probably get a custom harness made. Check a climbing store that caters to rock climbers. They have webbing and heavy duty sewing machines and could probably fabricate something for you. Unless you have TREMENDOUS upper body strength you won't be able to pull yourself back up onto a stand should you fall and be dangling from a harness. Look into a good ground blind and get home safe and sound. Good luck.
