OK, now with all these questions about which kick is which I am confused.
I assumed ( there's that word my teachers always warned me about

) that the siccors kick was what you use when doing freestyle mosly hips slight bend at knees. I also thought that a flutter kick used only you calfs.
As with most of you I vary kicks. I start a deep dive using siccors (for power + speed) then as I get neutral/negative I just use my calfs. This alows me to not use any muscles except the calfs and feet (relatively small?) muscles. I've found that when spearing i make less noise (visual and audial).
I've heard a lot of people talk about a dolphin for power but I can't seem to do it without expending vast ampounts of energy. It's not the "working" muscles that are using the energy, it's the muscles I use to keep the air "in" (diaphram, the little muscles between the ribs, etc). I've never had need to have such a "burst" in daily diving (only been chased by one big shark {mako}

I don't think I could out race a puffer fish if it was trying to get away from me.
Am I doing something wrong, or am I missing something? I am FAR from an expert in diving technique.
I just love this site
