I agree. I have said before that I also train in TKD, and on occasion have attempted a more aikido type move than a TKD type move in that class. In one-step self-defense, kotegaishi, shihonage, and a couple of kokyunages work well. But in full sparring, the most effective I have found is iriminage. If you can slip inside their defense and catch them extended... well, the look of wide-eyed surprise as their feet come off the ground is quite satisfying.
