I used thirty Vaegir Marksmen, twenty-five Swadian Sharpshooters and a Rhodok Sharpshooter I had captured at some point in time. I took three or so Hired Blades to fill out the ranks, but apart from them I used all archers. And no, I don't used battlesizer, but I do keep it at the maximum allowed in-game.... Been thinking of making it smaller, though, just to make it easier.
