I'm on their email list---some very tempting stuff here of late, especially the 15" Mastersounds. Unfortunately, I've spent all of my discretionary drumbucks on getting the three ply Luddies that I bought recently in playing shape (the drum equivalent of "The Money Pit" ).
If you read the description it looks like a regular K top with a Special Dry bottom.
They may have used the wrong photo ... but a phone call to them would clear it up. I am sure the entire stock of the Special Dry Hats in both sizes are long gone by now though. I cross posted this on Ghostnotes and a friend from Cymbalholics alerted me to the deal. Unless they had a pile in stock they mush have all been purchased considering how desirable that model is.
EDIT: Drilled down and your are correct. It is a hybrid pairing. Good eyes!
