I know that baritones are tuned 2.5 steps down, but I've never seen one tuned 2 steps down. If I was to tune down to C, or occasionally dropped A#, would it be wiser to buy a baritone and tune up, or get an extended scale...or...whatever?

I just wanted to make sure I wasn't doing anything wrong to the neck.

I understand that, but what would be the quickest and easiest?

A baritone for A# definitely, you could probably manage C with it too but if i were you i'd feel a lot better about having a 6 string with just thicker strings tuned down to C.
