Concerning Second Wind vs FlurryFollow

Hi everyone.

So my warrior is just about 68 and I wanted to start some pre-70 PVP grinding.
There arent a lot of pvp guides for warrior. I've searched wow forums and tankspot guides and I'm just looking for more opinions or an open discussion.

Basically my biggest question, is it worth dropping 1-2 points in flurry to pick up second wind. The way I'm looking at it, on a 3.6 speed weapon with flurry up (4/5) thats 2.88 speed (down from 3.6 on the weapon i was planning on using). With 2/5 flurry its only 3.24, and 3/5 puts me at 3.06.

So, for battle ground pvp, and arena pvp, is taking second wind going to hurt my damage much? Is that speed increase worth it?

Thanks for any input.
