JJ,
Super theme for your troop builds here, and nice blog post to inspire us around the thinking for your chosen approach.
I've also begun the transition of my rounders-based minis (but for an ACW collection), with plans to use them on sabot bases. Since I'm here in the USA, I instead went with a domestic producer for these - by Terrain Genesis, but Supreme Littleness were also tops for consideration.
We'll be enjoying seeing your pics/post as you move forward the project here!
