I bought some in B&H's last sale, with burnt orange I think. I've not used it a great deal yet as it's subsequently been outsoaped by Sante and MDC, but I will return to it.
I don't ever remember any problems holding lather, if I had any criticism it would have been that the lather had a tendency to dry a bit quickly, that said I didn't really use it enough to get the soap:water ratio right. Its worth trying some in my opinion. I've got a couple of MB's which have also been neglected of late, but its on a parr with them.
