This may be controversial but is SDK really mandatory for fast freestyle?
Don't see much of it here, it looks like they wan't to surface ASAP:

I know proponents will link to Phelps' 200 WR, but other than that, I don't see many people exploiting it.
Will we see huge SDK in freestyle at the upcoming Olympics?
I don't fly because of my back, so my SDK in freestyle is minimal. I'd like to think I don't need it.
I'm keen to watch for it in elite freestyle races and it is a mixed bag. Many are fast without a big prolonged SDK.

For those who aren't up on obscure swim lingo abbreviations, does SDK stand for submerged dolphin kick?
GJ, OMG, IDK, LOL, TYVM!
