Spot or Flood for Aux Reverse Lights

I'm thinking of getting something like these http://jasperoffroad.com/index.php/led-lighting/small-led-pods/6-slim-18w-led-pod.html
for extra reverse lights. I have a camper shell with tinted glass and I can't see out the back all that well at night. These seem pretty bright and low profile so I can mount one on either side of my trailer hitch.

Which would work better - Spot of Flood? Or one of each? Now that I'm writing my question I'm thinking one of each.

 

I'd go flood for reverse lights. No need to see 100' behind you while backing up but 30' behind you and wide would be nice, at least that's my $0.02.

 

flood.....spot would light up a small area and give u distance but sacrifice spread...ur not backing up at 65mph so I would fully weigh on the flood/fog pattern.

Having the surrounding area illuminated is much more important than whats a block away when ur backing up at a low speed.

Im with Fuggles on this one
