There's a lot to be said for CoachFlppr's idea. I had an nasty kick that seemed to be throwing everything else off. So I quit kicking altogether, now just keep my legs streamlined, feet together, and toes pointed. Balance is better, rotation is better, and my focus stays on the front quadrant. Net result for me: faster lap times and lower stroke count.
Maybe we all worry too much about the almighty two-beat kick.
