I chose to paint a load of skeletons to balance out my average. The reason I went for 24 rather than 20 is to fill the 12-slot movement trays I use for Kings of War and I didn't fancy leaving 4 models hanging over.
24 skeletons with light armour and spears are 312 points in 3rd edition, 264 in 4th. I'm not counting unit command.
This brings my total up to 632 points for 3rd edition or 444 for 4th.
Next month (January), I am going to add shields to the unit, 3 Carrion and 5 Cavalry.
