Alternate between the two, later on you'll get One Ilm Punch which is extremely situational for Raptor Form so it won't change much. At least fo rRaptor. For Opo-opo, you'll alternate between Bootshine and Dragon Kick. For Coeurl form, you'll alternate between Demolish and Snap Punch. The only time I've used Arms of the Destroyer and Rock-Breaker is for more than 4 ads with low health.
