That would explain it.
I've always had patch cables laying around, just waiting to be cut up, so I've never had to rip any out of the wall, or buy a roll of it.
If I had bought some, I would have bought the stranded stuff anyway.
I learned that early on buying single wire, and phone cable wire.
As for the quick disconnect thing, I soldered all of mine directly to the switches, so I didn't have to worry about that part.
