Nothing "silly" about wantin' stop your bike the best way possible
I'm happy with my Avid single digit 25's. Switching to disks seems like it would be pretty expensive when you add up "everything" that's involved. Unless you are having problems with your current setup (or you have lots of money) I'd stick with what you've got. But that's just me...If I were building another bike from the ground up, then Iwould take a serious look at disks.
