Ok, i am now starting brd and have made it to lvl 12 ! YAY !

I was wondering what would be the best Sub for a Taru Brd this lvl ? I have been using Whm, but i don't think i will really need that sub any longer and am thinking of switching ... but very undecided as to which one would be the absolute best

Can you help me out ?

Please and thankyou
