Thanks all. I totally agree that the three base look is better and am somewhat at a loss why I didn’t do that, as I usually do!
interestingly 3 x 40mm for my 12mm bases is 120mm and my 28’s are on 50mm bases, so three of those bases would only be 150mm, so just a 30 difference on the unit frontage between the 12’s and the 28’s.
Three 12mm units in the front rank have 12 men and three 28mm units in the front rank have 9 men.
That is surprisingly close when perceived wisdom is that only the smaller scale should grace the smaller table etc etc.
I just swapped out the bridge for my 28mm bridge, which has a relatively small footprint to see what that looks like and even that did not have a big impact on the table.
