An instructor that's been visiting classes gave me some advice on my poomse, Won-hyo, and I am not sure if I want to follow it or not. Normally when I do the sidekicks in won-hyo, I do my best to snap them back as quickly as possible, because that is what I would do in a fight to prevent my leg from being grabbed. But the visiting instructor recommended that I hold it out for a split second so that when in competition the judges can see how much control I have, where when I snap it back they can't tell easily. What I am afraid of, however, is that if I practice my forms like this then I will do it when I am fighting. A belt or two ago I used to hold my leg out for a split second when sparring, and often my opponents would take advantage of that. I had to really work at it to get to the point where I could snap my kick back quickly, and I don't want to do anything that could adversely effect that. what is your opinion?
