Well sabot basing is the best of both worlds. It gives you ease of movement when you are moving several figures at a time but figures can be removed and used individually if required.
Just a thought but I am about to embark on a project using Crossfire rules, but I don't want to restrict my figures to Crossfire. So I will use sabot bases for three figures. Three bases in a 'unit', two with three riflemen and the third with the bren, an NCO and a riflleman. For Crossfire this will be a platoon, for Battlegroup it will be roughly a section and I can choose to use the figures on or off the bases.
How that makes sense and helps.
