Rusty, when I began playing fives, I'd take the four with me to the gig, and after a half hour of OOOPS and SCUSE ME and #&%&$^@*~!!!, I'd chicken out and finish the gig back home on the four-string. So I explained to my fellows on the bandstand that it was just going to take a little while and I left the four at home. You may want to go back and forth (I'm not that smart or facile), but if you're going to play five from now on, I'd suggest leaving the four-string as a fond memory.
I also wouldn't let the S2 see the Schecter. Leave them alone in the same room, and you may come back and find the blue one alone with a 'who, me?' look and a pile of sawdust around the other stand . . . .
