i think mendis is an auto in this format, at least going by current stats (might change as we've all seen his fall in the other formats and it could happen in t20s as well). the other spinner spot i guess is up for grabs but when you compare swann to narine you're not losing anything with the ball and getting more with the bat, whilst ajmal doesn't add with the bat but has a lot more t20 experience and comparable stats to narine.
