You've twisted my arm. I'll use the Hammer. The spin looks ridiculously fun. I barely know what I'm doing as it is, so having the added problem of logistics makes ranged stuff sub optimal for me.
Careful with that. The main problem I had when learning hammer is accidentally spinning - you usually don't want to do that. So you need the self control to stop moving every time before releasing your charge.
The main use of the spin is that after the first 3 spins but before the last spin, if you press X it does a really, really powerful golf swing. It's situational but will - to put it scientifically - fuck shit up if you manage to land it.
Remember to always dodge after the end of your super pound etc to speed up recovery.
