3 point mirrors?

[Travis1974]

I searched and only found some old threads. I am doing a full resto on a 72 GMC burb and debating what I want to do with the mirrors. The doors look to have 3 sets of holes in them from previous owners. I believe it came with regular sport mirrors but is a 4x4 and had larger mirrors added later. I will be towing so I'm thinking of going to the smaller 3 point mirror.
I have not seen anyone mention the potential denting that can happen from these 3 point setups. Here is an old Chevy door that had a large 3 point on it. You can see the damage from where it got bumped.
Any thoughts? Maybe smaller 3 point = less potential damage?
I'll probably just patch all the holes and start over once I decide.
