Also you're probably playing too early.
the late cut is a good idea like said, but I find i struggle to time that and edge it to the keep quite often, if it's outside off i usually play the revers sweep instead, I struggle to time that just as much, but i never edge it, either miss or play it to the point area. always spoons up a little so i only play it if there is no forward/backward/regular point.
also once you can time spin remotely well it's really easy to hit anything straightish over mid on/off for 4/6, usually doing this twice forces mid on back and opens up the ones/twos to long on for quite a while, so one or two shots with some risk can effecftively generate 20-30 pretty easy runs
