OK, so I've always loved my WB Traveler, but this winter had an incident with a mouse that got me thinking about more coverage....I bought a WBBB on sale at Christmas and this weekend was the first time I've had it out....I really didn't want to like it because I felt sure I'd feel claustrophobic in it, but turns out I reallllllly do. So, now I need to know how you BB owners have lightened your up? I already use whoopie slings, bringing the weight to 15.4 oz. then I add my tree straps/alum toggles and that brings it up another 3.1 oz......for a total of 18.5...anyone trump that (without tree straps that would cut into trees)? Just curious if I could do anything to the bungee pull outs to reduce that extra wt.?
