Gerry,
I presume you are doing a Medieval Russian Army, I found the Fireforge Resin a bit rough. At the York Show I did some Russian Cavalry which I made from the Fireforge Turcopoles and the Byzantine Koursores. If you search on the Vapnartak 23 Reviews you will see some pictures of them, also on U tube. As I did not take any pictures myself.
My figures were based around 1242 AD, but the Russians were a bit old fashioned in some things.
