While I love long hair, I tend not to like super long hair. There's something sort of '70s about it and it can be a drag. I think yours looks gorgeous though. Thick, healthy and not stringy at all. Super long hair has the tendency to look stringy and straggly towards the ends. I'm sure you've seen what I'm talking about. So yeah, in this instance, I'd say go for in between because your hair is just plain gorgeous. If that doesn't do it for you you could always go shorter. I love short hair too. It's just it can be a pain to grow out if you decide to change your mind.
