I am still using the spec from the OP, for comparison purposes.
This set simulates out to:
~25660
chardev 8 - Cataclysm Beta
CharDev does not calculate the spell hit correctly. There is 1757 rating on this set, which gives 17.15% spell hit.
I found this set by simply calculating EP values from the current BiS set in the OP and then plugging those into the Mr. Robot site. I also forced DMC: Hurricane to be selected as one of the trinkets - that one is hard to estimate with EP values:
Mr. Robot - Enhancement Shaman - World of Warcraft
Note: If you follow this link, the Mr. Robot site uses a default enhance spec with only 1/3 elemental precision, that is why you will see the hit % on Mr. Robot showing a little lower than what I use in the config file.
