I can compare. Just the right length is very nice, even if you weren't asking about other (small) differences in weight.
If this proves to be good to 35-40, then you will or should care then about the snaps and tie at the top.
I've tried omnitape for the footbox from two vendors. I really don't want to be curious about how much of it has come undone later in the night after I've heard early in the night the sound of partial separation getting into it. HG's 3-4 snaps have done me well, and maybe one top snap would improve those omni-taped products that I accidentally kick partially apart getting in.
Repeat: Don't think just about hot summer; think ahead to fall.
