I've been using my HH Explorer Ultralite for the past 2 years and enjoyed the bottom entry well enough. When I saw the Zipper Mods by 2QZQ I went with the Mod 2 option (Full zip one side, 1/2 zip on the other with tie-backs for the bug netting where it's still permanently attached). I chose not to sew the bottom shut simply because I like having the option there, just in case. I have not really tried the new mod in the field yet, just in my basement trials in and out, zipping it up from the inside, and setting things up seem easy. I do like the versatility of being able to just get in without having to crawl up and in through the slit, just plop right down once the bug nettting is zipped back. The thing I like best is that it gives that extra bit of versatility without having to have a separate bug net to set up, or not having a bug net at all when you need it.
And for all you gram weenies out there, after replacing the ropes with whoopies (my first hammock mod ever ) it's still lighter than it was stock
