The recent swift thread got me thinking... I was hoping to get a Birkin in a smooth leather and presumed I would want box, as I have experience with this leather and its longevity and patina appeal to me. But now I am wondering if it is worth considering swift instead? It is more matte than box and more supple, I think...beyond that I don't know if there are other qualities I should be comparing. Also, are there other smooth leathers I should consider? I think evercalf is too fragile and can't think of any others...I already have barenia (my fave H leather of all).
