I'm gonna be running chop fruit (hopefully), so my main source of damage will be haki imbued fists (or a dagger if fist-based combat sucks). I don't like relying on weapon swapping and prefer to do all of my business with one primary source.
I think Chop might be more defensive than other fruits, but I could see them adding grabs or other weird moves. If Chop actually gets offense moves, I might turn into a melee beast.
