I tape the key down as well..lol. But another way to do it is just remember where you put them.
I usually put 2 tank spirits, then back up a bit, then SoS, then back up a bit more and put my blind/interrupt/etc in the back. Once you get used to placing them in somewhat of an order, its easy to remember which is which without the tape.
Spreading them all over the place usually isn't the best idea since they "spray dps" rather than focusing. Usually I try to keep them close together, but not on top of each other.
As for the guy that said he just recasts each time the cooldown is up, that can lead to a mess in some situations and I wouldn't suggest that. If you recast your tanking spirit while it is tanking, the mob AI might decide you look like the next best target
the pic might make more sense. (Pain and Bloodsong being the frontline, me standing in the back with the weaker ones) ->
