Finger Whistles or not?

[SouthGARef]

I use a whistle at all positions. When I'm a wing, I use a lanyard whistle as well. Before the play starts I keep the lanyard whistle in my mouth in case of a dead ball foul. At the snap, I spit it out and use the finger whistle to kill the play.

I feel the finger whistle gives me more control and agility. While I don't like to see refs giving "half signals", I don't think this is hard to do. I simply don't signal until I've blown the whistle, and have enough time. I'm in no hurry to signal a TD or anything, one extra second won't hurt anything.
