RE: Have you tried the new Summit portable?
I have not tried any of the newer hang on stands from Summit, but judging from the quality of all their other products I would say these two would be excellent stands. I have yet to try a Summit stand that was not good to excellent in everyway. I really liked the old Copperhead XL hang on stands, very comfortable and easy to hang. You could also adjust it to fit not so straight trees.
