Which is a better fit?

Coming from a Single Wing coach, I'd like to answer, "Single Wing" as the SW is the greatest formation for the misdirection. However, with the two choices mentioned, I'd go with the Wing-T. The Wing-T allows for a better separation of receiver/defender due to the boot-option series. Also, it's easier to install the 'Jet Sweep' series - a real staple of any Wing-T team nowadays. While both the DW and Wing-T work on angle blocking, the Wing-T - in my opinion anyway - allows for more of a passing threat...even if you only throw the ball 10 times in a game.
