WotLK BiS trinket for Assassination PvP?

[Rahmeek]

Playing belf assassination rogue and need a little help on picking the bis trinket for pvp. Trying to avoid sts and dbw because arp is useless for envenom pvp.

sts still gives the highest ap boost, closest is wfs hc maybe but dunno, I would use sts.

[Persivaln]

You WANT STS due to it being highest AP proc in game with good uptime/icd. DBW is gamble + it have long CD. And even if you use envenom, arp boosts your damage from attacks, especially against cloth armor.

WFS HC is always a good option since any spec makes use of crit and AP. Also the proc uptime is nice.
Still STS HC wins simply by being 284 vs 264, thus having more stats. Even if arp is less desireable you get a shatload of it + the proc is literally the best AP proc you can get hands down.
