that's tough... My go to is the black PDP with magnetic back. I use that a lot.. I own three of them actually lolWhich is your fav?
And that's the first 20-lug 16x20 I've seen.It's a 16x20 and holds 20 keys.
What do they sit on? Screws?
BTW, those pictures would make for a great riddle for the uninitiated. I wonder how many non-drummers would have a clue what they're looking at.
