Just got my Whoopie Slings from Whoopieslings.com. Got them really quickly. Can't wait to put them on my Hennessey. Just like everyone else here, I will be buying from these guys again. Kind of funny my 8 year old daughter will sit by me reading a book for school while I "study" hammock camping. After receiving my Hennessey Expedition with the complimentary Cub, I was watching TV one night and out of the blue she asked "Are you going to put Whoopie slings on our hammocks." She said "Shug likes those maybe we should try them ." I got a belly laugh out of that. Maybe she was paying more attention to the "hammock study" while reading her book than I had realized
