I would suggest find a piece of fleece and making your own fleece saddle and standing on ground level. I literally just nail 2x4 and a piece of plywood the size of a platform at the trunk of a tree. You can use safety harness that come with any tree stand as a tether, cut pieces from it to make bridges etc, good knots even with webbing will do fine even if you dont have a sewing machine. If you just want to understand the principle and mechanic of saddle hunting, that is the cheapest way to go. Then if you feel comfortable, I suggest the TreeHopper Recon Sling.
