How many types of calf leather in Birkin?

[joycep]

Hello all,
i'm a newbie. i wanna know how many types of calf leather are there available now in a Birkin?
anyone knows which is more expensive and the leather characteristic? vein/no vein/structure/smooth/slouchy/soft etc?

i find Togo a little slouchy for me. but i definately don't want a Box...so what can i go for? Epsom?VL (but VL is more ex right?how much more?)and what else?

any feedbacks are welcome. thank you for your time!
