i cover my Night Owl with a Tadpole and all is well. i have not been caught i a high wind and rain situation yet, but coverage should be fine.
the Lazy Slug Tube is to my sleep system what "skins" are to my tarp, kinda.
with the tarp...hang and tighten the ridge line (in my case a CRL) pull back the skins and voila- instant tarp.
with the Lazy Slug... hang the tree straps & toggles, attach the whoopies, pull back the slug and instant sleep system.
i really like it but i am a lazy slug
here is another thread on the LST.
right now i have 2 lazy slugs, loaded with complete sleep systems (described in the above mentioned thread) in my ALICE pack.
oh yeah..i'm just a fan too !
