Copper Cartel Limited Edition Question

Hi All, new to Mech mod and need advise from the pro if i should drill vent holes on the mod.
if yes, should i drill on the top or bottom?

For a 18650 mod a few extra vent holes would usually be an OK idea, the problem is doing it without spoiling the looks and getting them in a place that actually helps. Can't really help for this mod as don't have.
For a 26650 mod it's fairly pointless as the battery will vent with such force that you are going to get hurt no matter what, vent holes will stop it turning into a pipe bomb, but I think you would need loads of holes for this.
Smaller batteries obviously vent with less force so are less dangerous.
