Can someone answer something for me? When using longfins, what is the optimal flutter kick amplitude? A buddy said I was overpowering my fins by using excessively wide kicks. He advised rapid, low-amplitude kicks, no greater than the draft created by my body flowing through the water (~12-16 inches). However, someone else mentioned that kicking in the turbulent wake created by your body is inefficient, and you should kick wide enough to clear this wake. What is the correct technique? Sorry for the newbie question.
