I'm the kind of the guy that says :
Galder Throw is only for 1 Power Charms (maybe even 2)
You're 4, GT it weak for you
So, either :
A) Get PB and TW
B) Only get TW, save your TM for 2nd job instead of TW
C) Get none and save up to 20 TM points (Slower leveling, but worth it in the end

)
Also, side note :
I prefer Galder Throw, for not being a melee guy
