Serious Answer: I stick with one finger because I often transition into finger guns from a snap, to add a little pizzazz to it. If I try it with two fingers, my middle finger comes out slower than my index, as its the finger I use to snap. However, if one chooses not to transition from a snap, I would heavily recommend two fingers, both hands, one slightly in front of the other, followed by a wink and saying the phrase "You're pretty good."
