Andreas has dub flat 9 both ways, dub 10's both ways, and dub 12's both left and right. I bet he's done switch dubs both ways, but couldn't say for sure.
Bobby has some rightside dubs under his belt... Pretty sure just 3 directions though, not 4.
Wallisch has dubs in 3 different directions... Wouldn't be surprised if he also had the right dub 10.
Russ can do dubs three ways, maybe all 4... not sure.
LJ can spin dubs to three different directions, but they aren't all the same dub.
Chug spins right and has dub 12's and switch left dub 10's. I've heard he has the switch right dub 10 too, giving him 3 of them, but I've never seen it.
Pretty sure that's it...
