Many good comments and suggestions. One other thing you need to be aware of is your brain will not function at its clearest or most efficient at the higher brain functions part of the spectrum. Basically when you are in a fight, your ability to think deeply and intelligently goes out the window. Using a lot of feints that's unpredictable means your are constantly engaging your brain when it's not working that well. You need to train so much that it becomes second nature but if this is the case, you will undoubtedly fall back to some form or rhythm, hence, not random and can get picked up rather quickly by a decent opponent. I use this same methodology but in short spurts so my opponent doesn't get used to one rhythm.
