You're starting off with 2 heavies or 2.5 mediums. (well, at least I am, the only heavies I have cost 5, which isn't more than the 4 my mediums cost)

So my usually lead out is usually either a heavy and a medium, (enemy coming in more than 1 lane) or a heavy and an art. (enemy coming in 1 lane) With the next one out usually a TD.

(Incidentally, game really needs a way to set a threshold at which you auto-recycle emblems, since unlike tanks recycling is all there is to do with them.)
