Tailoring Specialisations @ 350

Has anyone looked at the various tailoring specialisations available at
skill 350?

My tailor is an "elemental" spec mage, so going the spellfire route may
offer some nice items (very heavy in +dmg) but I'm weighing that up vs
the mooncloth specialisation and "double" primal mooncloth which is
going to be in demand (in a big way) by people looking for 20 slot bags
and other items.

Since Blizz haven't allowed (yet) tailors to re-specialise (for a fee)
if you want to change spec you'll need to drop tailoring and level it
all over again - not a massive hardship (maybe a couple of days and
100-200g).

Anyone put any thought into it? I'm really confused about which way to go!

Cheers,

Mike.
