Someone has already done Quick Ball for FS metang, so I'd say keep.I'm not posting to brag, I just want advice.
I just caught this Metang:
Metang (Adamant):
HP: 30
Atk: 31
Def: 31
SpA: 24
SpD: 28
Speed: 31
Should I keep going? I've only encountered 2 5IV Pokemon in the friend safari so far. Also, I caught this one in a Net Ball, but Quick might be better for Mega-Meta?
