I carry a set of RCA > RCA and a handful of RCA adapters, primarily RCA > 1/4", RCA > XLR, and RCA > 1/8".
I think that I may still have a pair of RA XLR > RCA hanging on my bag too. Probably out of habit.
My back recently reminded me that I need to slim my gear down too. At least the SLA and DVD batteries are all gone.
