Mindy is way too fast and agile for him IMO. I was more impressed by her stomping some of the Mother ****ers guys, aim timing and dodging bullets and killing Damicos guys as well than anything Bale did outside of Batman Begins. The best you could argue for him is he had a strength and gear advantage, but go think that's negated by the fact she is more agile and can stab her with that pIKe
Solid fight but Id roll Mindy
Standard gear for HG is at least 2 guns. A sword-staff. Knife. And the kunai rope.
She's also waaaaay faster, and has experience fighting bigger stronger people who are a whole lot faster than Bruce. She's not gonna waste time. She's gonna shoot him, and if that doesn't work she'll get close and gut him.
