I'm hedging a bit and saying gradual long layers, just because it might give you what you like about layers without the shortness or the risk of stringy ends.
Every once in a while I want to grow out my layers, but when I have had hair that is one length, it has been so thick that it hasn't hung well. Our hair is different, but I think it's the thickness that makes my hair want layers rather than the type of curl. HTH.
