I am gearing up my druid for PvP. I have created this macro for attacking using ravage when in stealth and shred when not in stealth. I was wondering is it possible (and what would it be) if I wanted to also bind Lacerate to the same key when I am in bear form. Otherwise it casts the other two abilitys. Can anyone send me some help? Also if you have any other useful macros for druids I would welcome those along with the one I want.

/cast [nostealth] Shred
/castsequence [stealth] reset=6 Ravage
/stopmacro [stealth]
/startattack
