That stand is a lifesaver!
Don't know if I have a favorite. My collection is constantly in flux, with trades and CL/ebay deals. I do have a handful of "forever" guitars though.
My 72 lp special, Cp jazzy, 68 martin electric, Lp standard, 50's tele ri and tele custom ri off the top of my head. If i had to dump most everything these would be what I try to keep.
