enhance shaman spec for raiding

I'm having trouble trying to decide. This spec http://www.worldofwarcraft.com/info/classes/shaman/talents.html?tal=500030000000000000000000305052031050213533110120105100000000000000000000000000 is what i tried out last night. and im not seeing a huge issue as far as mana goes for the most part. and im considering changing my spec to http://www.worldofwarcraft.com/info/classes/shaman/talents.html?tal=500030000000000000000000302052031050213533113120105100000000000000000000000000. this change grant me ~600 spell damage at the cost of 6% INT (which btw now increases my AP as well as enhance) . i think im going to test this and see if it boosts my DPS

k, so in the new spec i am seeing more mana issues like i expected, but i also saw about a 300 dps increase on average.

and just for amusement, in hyjal last week i was critting about twice as much as i was hitting XD

Hows it working out for you now?

im seeing about a 200 DPS increase with losing the int in favor of spell damage. Im also seeing more use in the SD while im taking damage or out farming, as my heals are MUCH more efficient (my healing wave went from ~2k to closer to 3.5k and they are critting for ~6k) so its actually allowing me to use less mana when healing is called for which is nice. The only tihng that im noticing is that im missing more than i was before, wherabouts of 3% more so im having to stack hit instead of just agi.

K, so since the patch ive seen a tremendous upgrade as far as DPS goes. But now im seeing a serious issue with my hit rating! i went from having a miss of about 1.5% to over 10%! WTF is up with that, i now need to stack a massive amount of hit in order to compensate, though i guess in all fairness it is the way it should be, every oher melee class is forced to stack hit. Now i actually need ZA for the coif of the jungle stalker from malacross X(
