I still submit that there are THREE standard phaser options based on what we have seen in TOS and TOSfilm. There is STREAM - the long continuous phaser beam we've seen time and again. There is PULSE - the fast short pulsing phasers that we've seen from WOK. There is BURST - the single orb shaped phaser blast seen in a handful of episodes.
Good points! I guess we will ignore the WOK since that is much later. But what about BIURST as you say? What episodes is that in? I will check it out.
