First Base

First eight finished. Not sure about basing yet, depends on the ruleset I go for. At the moment it looks like FOG (in which case the 60x40mm base would be right), but I do have a tendency to change rule systems like underwear.

Before I base them however, I'm trying to work out where the 'file leaders' should be in relation to the phalanx. Logic dictates they should head each column, but that would mean too many file leaders on the front base. So if anyone has any ideas please share them.
