Had my bottom entry closed ... cause ... no reason in particular other than I just ended up not using it so much with my first mod ... so when Donna made a Mod 4 out of it ... I just had her sew it up. Here's my review of the Mod 4

Had the Mod 4 done on my HH. I had the bottom entry closed because I wanted to sleep w/out the slit under my legs and have the area under my shoulders and back as smooth as possible. It is more comfortable for me that way. I have another HH side entry and from my experience w/that one felt I could live w/out the bottom entry. As w/most things, there isn't an absolute right way. For me the benefits outweigh the loss.
As for 2QZQ and their work, all I can say is, excellent!!
You will not be disappointed. I agree with the others...mine was worth every cent. I have to admit that I don't use the bottom entry much since I got this mod...only time was in a rainstorm where I had the tarp pitched really low and tight, and it was easier to get into the hammock that way without brushing the underside of the tarp.
