How many deliveries does Narine have?

How many deliveries does Narine actually have and which does he use an illegal action on?

As far as I can see, Narine has his stock off-spin delivery, which cuts left-to-right. I don't think he "pelts" this one. He seems to get success with his stock ball because he bowls very flat, and can control well the amount of turn he gets.

He also has the doosra. This is the opposite of his off-spin. Everyone says his action is illegal when bowling this one.

He also seems to have a carrom ball, which I believe he can finger spin either left or right. Not sure.

He then has a slow ball, which is either dead straight (no spin), or slow and off-spin or slow-doosra.

And of course he has his "faster ball", which has the same three options as the slower ball except he PELTS IT LIKE FYAH.

The doosra tests batsmen's skills. Even if it needs relaxation like 18-20 degrees it should be allowed - Rameez Raja:

An off spinner cannot get the ball to go the opposite direction without a reverse arm.

To do that : he gotta Pelt !  :-[
