May I get an opinion on macroing Fang and Claw and Wheeling Thrust in a single button ?

Like such:

/ac "Fang and Claw" <target>
/ac "Wheeling Thrust" <target>
Since both are mutually exclusive, will it kill my DPS due to some obnoxious delay if I just smash the button when I do get a proc ? Just wanna prep in advance, a reply would be much appreciated !
