WotLK Bis pvp hunter trinkets

[Xoolll]

Hey guys, I'm going to buy a trinket for my hunter since I only pvp. I'm playing MM, 6.2k gs. Currently I am using insignia and key. Which trinket would be best? Sts, death's choice, or anything else?

Thanks in advance!

sts for sure.

sts for sure.

Is the armor pen so superior for pvp? Is there even a recommended amount of arp to aim for? No guides seem to focus on it.

"Armor Penetration. Is it worth gemming? Not in PvP gear. ArP only does well when in high amounts (50%+), however, it is not a useless stat. You should get loads of ArP from 284 ilevel items such as the trinket Sharpened Twilight Scale (heroic), Oathbinder (Polearm), Returning Footfall (Feet), Fal'inrush (Crossbow) and other PvE pieces.
ArP should only be gemmed when playing PvE. Just gem straight Agility or Attack Power. Most hunters will tell you its a complete bad stat; which is not true on icecrown where you can get all the best gear in which all your PvE gear gives ArP and high agility."
