So after doing some searching on wowhead last night I was a little angry to find out that the green quality gems in wotlk will be better than the epic gems in bc.

http://www.wowhead.com/?item=32196 (+12 spell damage) vs http://wotlk.wowhead.com/?item=39911 (+14) or http://wotlk.wowhead.com/?item=41438 (+16)

Recently I had gemed for pure spell damage. Now I am sitting on ~175ish badges on each toon with almost nothing else to spend them on. So if you wanted to gem my current gear how would you do it?

Head: http://wotlk.wowhead.com/?item=32011 Merciless Gladiator's Mail Helm 1 red 1 meta (+4 resilence bonus)

hands: http://wotlk.wowhead.com/?item=33534 Grips of Nature's Wrath 1 red 1 yellow (+4 spell power bonus)

chest: http://wotlk.wowhead.com/?item=34933 Hauberk of Whirling Fury 1 yellow (+2 spell power bonus)

legs: http://wotlk.wowhead.com/?item=34934 Rushing Storm Kilt 1 yellow 1 blue (+4 spell power bonus)

belt: http://wotlk.wowhead.com/?item=30044 Monsoon Belt 1 yellow 1 blue (+4 spell power bonus)

feet: http://wotlk.wowhead.com/?item=33537 Treads of Booming Thunder 1 red 1 yellow (+3 Critical Strike rating)

wrist: http://www.wowhead.com/?item=33897 Treads of Booming Thunder 1 yellow (+2 resilence bonus)

ring: http://www.wowhead.com/?item=34625 Kharmaa's Ring of Fate 1 red (+3 stam bonus)

what i really want to end up happening is getting http://www.wowhead.com/?item=34220 (Chaotic Skyfire Diamond
+12 Critical Strike Rating and 3% Increased Critical Damage) as my meta but that requires 2 blue gems. So what do you think i should get?
