After contemplation of whoopie sling toggles, and rejecting things like wooden dowels, I roamed the aisles of Orchard Supply Hardware and found these.
The wire gate would keep the post from sliding free. The post is not hollow. They weigh less than the large climbing biners I was using with the stock Warbonnet straps. About two bucks apiece... haven't hung with them yet on the whoopie slings. It takes significant force to open and close them, but it's not hard to do.
