It's been a while, but there is a video somewhere on youtube (or there was) of a Russian aikidoka and a Russian Thai boxer sparring. The aikidoka was able to pull off a kotegaeshi from the boxer's jab.
They were very well matched, but the aikidoka certainly held his own. It wasn't prearranged and they were certainly going all out with each other. It looked like a good match up honestly. Can most aikidoka do that? I doubt it. But to be fair the Thai boxer if memory serves was a champion in his weight so maybe a less skilled Thai boxer wouldn't have done as well?
This weekend we were practicing Daito-ryu against jabs instead of lunges and shomenuchis and found if you do the kata correctly they work juast as well or even better if someone pulls back their hand.
Good luck, keep training and don't be to eager to show off your skills because you don't have any yet. Part of budo training is to supress the ego, this should be a good lesson in that.
