Best pvp trinkets

Hey guys,

I was wondering what's the best PVP trinkets for enhancement shaman, i googled everywhere and there are a lot of conflicting opinions between Whispering Fanged Skull, Comet's trail, Herkuml War Token, STS, and Tiny Abomination in a Jar.

I'm utterly confused.

And if it comes down to Comet's Trail or Herkuml War Token, which one is better if i'm stacking AP?

I'd say dbw, because of the length of the proc. Usually your trinket will only proc once in a duel, so personally, I'd rather have a 30 second good buff then a 15 second great one. But it's up to you.
