I have no experience whatsoever with H (yet

), but I can say that I will never ever buy another piece of lambskin. I got a fendi spy in lamb nappa and it just fell apart. Now there is just a big gaping hole in one of the corners - it's so big I can stick my finger through it. I went back to the store and they said it is because lambskin is very delicate. They can repare it though (that basically means stitching it). If I were you I'd stick to calfskin, which is much more sturdy and will last a lot longer. Good luck deciding (and do post pics of your lovely case when it is finished)
