Damage and pudding

I have always assumed that the +20 to-hit from a Burst-fire attack was due to using the extra bullets to saturate an area in order to hit the target, what is referred to as spray-and-pray. What if I wanted to try and concentrate that fire to deal more damage to that nasty Sathar attack monster?<br />Here are a couple of ideas I have had running around in my keg.<br /><br /><b>Concentrated burst-fire:</b><br />&lt;Edit: Remember that a Concentrated burst is fired at <b>one</b> target.&gt;<br />Option 1: The shooter can choose to increase damage by 1 point for every point of the +20 he sacrifices. Can use no more than those 20 points.<br /><br />Option 2: No bonus to-hit, increase rolled damage by 50%.<br /><br />Roll those thought around your mug and let me know what you think.<br /><br />Later I will pour in a few more ideas about burst fire and shotgun spread patterns.<br /><br />Edit: Final consensus <br />Option 3: Concentrated burst-fire will provide no bonus to-hit, but adds 2 dice of damage for auto-pistols and auto-rifles, and adds 4 dice to the heavy machine gun.
