I'm also between APL and BSL. I think I'm at about 24.5" right now, and BSL is going to be somewhere around 27" for me.
BSL is my next mini-goal, with waist following hopefully not too far behind, and hip following that. Once I hit hip, I'm hoping I'll be able to consider my hair long (there isn't such a thing for me as long ENOUGH). I still think of it as short right now.
My ultimate goal is terminal. I don't know exactly where that is, but I do know it's someplace below knee because I've been at knee before!
