That would depend on whether or not you adhesive the art or just lay it on, I guess.. hadn't occurred to me since I plan to adhesive mine.
Also, though, you'd have to be OK with removing pretty much everything to get the 4-way stick out (should the need arise)..
But I don't get it.. and seriously, here.. how is it in any way easier to route above the CP than below it..? Or is joystick height the main concern there..?
