Right arm legspin. I stand next to the stumps, walk down 7 paces, and then 4 paces diagonally to my right. That's where I start bowling. 1....2...3...4...steps walking, nice and easy, look around at the field, where I want to bowl...then waltz in casually and however I feel comfortably towards the stumps, right and left arm rise to my head, pick up speed, left to aim, right holding the ball, grip tightens on the ball, right hand comes down to chest, left stays up, pick up speed, right keeps falling down to the waist, nearly running for like 2 steps, small jump, land on right foot just before bowling, nice long, easy final step, whole body turns, right arm comes over, ball is released.
I ran up and down with my action like 7 times to get all that down. It's the easiest action I have so far, and I plan on using it a lot.
