Yes, I emailed Shannon yesterday and she said she no longer makes rolled collars. She said
"The kangaroo martingales are a much nicer product, however, they do not have snaps on them. The only thing that I could possibly do is put a small snap on one end of the leather portion and you could snap it to the other floating o-ring on the martingale chain. The kangaroo leather allows you to have a much lighter product, without sacrificing strength. Most of my Sheltie customers prefer a 6 strand, but it is more personal preference. A 4 strand is strong enough, but it is approx. 1/8" wide. An 8 strand is about 1/4" in diameter, while a 6 strand is a little less than 1/4", depending on the cut of the lace. I've also never heard any complaints about kangaroo breaking coat like some other collars."
Now, I guess I just need to decide what width to go with. 1/8" seems too narrow. Do you have the 8 strand or 6 strand Barb?
