Taste fatigue is not a problem when you're flipping between 10 atty's all day.
(For the record: 1 ZAP, 1 Odysseus, 1 Cobra, 1 Penelope, 1 Reactor, 2 Vaperfexion carto tanks, 1 blown glass alien head, and 1 ...umm... generic glass tank of some sort, all filled and good to go.)
I keep it down to two or three at the office, though.
