Need help with smoke trail from rocket

[composermanII]

I am working on a heavy-lift rocket model and I am running into trouble with the smoke plumes from the solid rocket boosters. I got the flame pillars to look great but the smoke is not working. For the flames I used 2 hve emitters and wind effecters. Anyone have any ideas on how to make the smoke plumes work? This is an animation if that helps. I am looking for the appearance that the space shuttle exibits in flight.

Thanks,
