Just finished rigging my Superfly and wanted to share. I followed the "carabiner around the tree back to the line" technique from the stock BB suspension and use plastic fig 9s for tension.
First, no hardware in the stuff sack. Hardware is contained in the outside of the two clips on the S-biner, and then I clip the drawstring for the stuff sack (behind the cordloc) on the inside clip of the S-biner. Slippery half hitch the loose end of the drawstring. Looks like this:
Unclip hardware / hardware into pocket / ridgeline is slippery half hitched to rings and uni-knotted to the S-biner / S-biner around tree back onto the line / place figure 9 / pop the half hitch and setup:
I handled the doors as Brandon recommends, with shock cord and loops over the opposing corner stakes. For binding the doors on the inside I tied an additional loop and then capture those on the inside with a NiteIze mini plastic S-Biner. Looks like this:
Anyway, thanks for the audience!
