many moons ago i submitted a kick check for tiers i've never been happy with it. this one how ever. I'm well happy with. so i might as well share some thoughts on kicks and checks.
also if you miss the check it can become a. catch
now to the attacking side.
I prefer low kicks to high kicks on the grounds it helps avoid kick catches and can be replanted faster if you pull out of the kick. the down sides include your knee being more vunerable to fracs and hyper extension dms if its the knee that hits.
I aim for the hip with the toe or shin. The front kneecap with my toes or side of the knee with shin contracted ankle to form a hook. It can be combed with a knee. to follow up or turned into a leg sweep with your hook.
when you replant your foot you should aim to protect your weak plane as a priority and attack theirs as their secondary.
