My full bag ia in my signature...though I also keep a CE TL, a firm Lace and a D4 depending on the course. Its more of a comfort thing to have multiplies of nearly every disc, just in case I lose one (which happens a lot.)
I also have a 150-class bag for when I hit up Japan that just has 10 discs in it. So I can get by with very little discs as well. Like I said, for me its mostly a comfort thing.
