Unbased figures

There are 10mm armies waiting to fight the ECW and AWI.  All of them crying out for basing.  Somehow I cannot decide on a scheme which will satisfy my allegiance to several rules sets at once.  Despite my ODGW connection, I do play other rules, and currently, but not permanently, we do not have an ECW set. And just yesterday some more English Civil War guys just showed up.  Time to get to work.
