What about reverse swing?
I love bowling reverse swing. Touch wood, I have control over it, but I don't think in cricket anyone is a master. I have better control over lengths but it all depends on how good you feel and in what rhythm you are. You can bowl seven overs on the trot when you are in rhythm; if you are not, it's a struggle to bowl even five. Some days you just wake up happy and everything and everyone around you feels good. There is this happy atmosphere around you. You go to the ground and feel you can do whatever you want. I think all fast bowlers know it.
