I find the firing line much more appealing than the "at ease" box. I already did or will get a box of each of the napoleonics you now produce. The firing line box would complete the Strelets battalion. Like many other posters to this thread, I also build up units using just one manufacturer, as the style varies substantially. And the shooters from the other sets stay with their respective units. Thus, we end up with a need for a Strelets firing line.
Graeme, I am very impressed with your conversions. Bravo. Thank you for showing the potential of some really annoying figures in the Esci box.
