In fact I rarely spin. I don't do spinning hook kicks too often. I don't do spinning roundhouse kicks too often. I don't think I threw more than one spinning hook kick during the whole Olympic trials. It just goes to show you that if you have good timing and can change the rhythm, you can throw people off.
Speed is relative.
When people throw multiple kicks, you can still time it and throw a kick in the middle. A guy that's awkwardly bouncing around is going to be the person that is hardest to hit, because there is no rhythm, there is no timing, which leaves you guessing. So that's what I try to do with people. I don't fight the same style every time. I don't fight fast all the time.
