DeanoZ,
I think that this is the one I am using (bought 2 of them):

I also think that I ordered the strap at 8 ft. long (you can always cut the excess on an angle and melt the end with a lighter) but, at that length, I don't have a problem with any tree I hunt from. I chose the black coated ratchet with a "woodland camo" strap. They have just about any strap configuration you would ever need. I also use an old spring-loaded cam buckle from an old strap-on style tree step. I place that after the AmeriStep steps are on the strap. This way, after I remove the ratchet strap from the tree, I can move the cam buckle up to prevent the AmeriStep steps from clacking together.
I continue to use the Sticks because I hunt a lot of public land and some private land. I don't want to damage any trees on the private land that I am hunting. And, in PA, on state land, you simply are prohibited from using anything that will damage the inner bark (cabrium) of the tree...a.k.a. no screw-ins! [:'(]
Hope that helps!
Joe
