Skull Bash Macro for bear/cat?

Looking for a macro that would check forms and use the correct skull bash for whichever form I'm in--or whatever is closest to that. Pretty much whatever would be better than just putting them both on a button and letting the wrong one fail.
Man, these types of macros are all over the forums. Try a search.

But since I'm here already:

#showtooltip
/cast [stance:1] Skull Bash(Bear Form); [stance:3] Skull Bash(Cat Form)

For anything generally:
#showtooltip
/cast [stance:1] BEARFORM ABILITY; [stance:3] CATFORM ABILITY
I also use a mouseover to mine as well so:

#showtooltip
/cast [@mouseover, harm, stance:1] Skull Bash(Bear Form); [@mouseover, harm, stance:3] Skull Bash(Cat Form); [stance:1] Skull Bash(Bear Form); [stance:3] Skull Bash(Cat Form);
Here is mine. In caster form it Cyclones.

#showtooltip [stance:1] Skull Bash(Bear form); [stance:3] Skull Bash(Cat Form); [nostance] Cyclone
/cast [stance:1] Skull Bash(Bear Form); [stance:3] Skull Bash(Cat Form); [nostance] Cyclone
