I like it a lot, but I have come to have a but.
A big but what if.
On my last hike i came across these small fellows who were all over. On top of my tarp, under it and all over my mosquito netting. Luckily I was in my WB Traveler with WB mosquito netting.
Had i been in my WBBB they would have come in-between the hammock and the HG under quilt, messing it all up.
As with the WBBB there could be a problem with your setup.
Just my 2 cent.
