After receiving tonnes of feedback (from an earlier posting here) both on here, via email and the various forums I am a member on, I have decided to go with a single rank of 6 figures.
Prior to that a squadron looked like below with the width doubled out:
A squadron will now look like this. Double the width but also more figs fitting onto the base:
The figures are literally boot to boot and I think gives a good medium between the double width basing and the mass I was trying to achieve. So regiment of 480 men in 4 x squadrons will being 16 figures, they will now be 24 figures. And instead of Cavalry matching the Infantry at 1:15 ratio, they will be 1:20 ratio.
As usual comments are more than welcome.
