Don't sign your posts. Also don't answer bad posts, report them. If your reply is "Use Rawr" that is your big red flag that you should be reporting it instead of replying to it.
Chainpullz, I suggest you use Rawr to evaluate the difference in value between ArP and Str gems.
I quickly loaded your char into Rawr and checked the most common raid-buffs (excluding Sunder Armor). When I opened the gem-template editor (which decides what gems to advise you for sockets). I noticed that the Arp/Sta gem was _slightly_ (very slightly) better than the Str/Sta gem.
You should, however, do the evaluation yourself, as I cannot know what classes (and thus raidbuffs) you usually run with in 10-man.
