I have a 1.7 Double Blackbird.
So far, the few nights I've spent in it have been relatively warm, except for the times I rolled off of the pad. So, the pad doesn't really slip out from under me.
Does this negate the need for an SPE. I've ordered a large SPE from Ed Speer and it will be hand delivered at the Hot Springs hang in a few weeks. I still want it, just in case I ever use a single layer hammock, but is it overkill to carry a full Wallyworld CCF pad and then trim down a second pad to stuff the wings finally putting the SPE between the layers of my hammock?
I got the large because I'm apparently an active sleeper and it seems to offer the best coverage. Anyone have experience with a large SPE in a double layer BB?
