I think I'll just 'suffer' without the smoke. If she wasn't running, I would, but not just for smoke. Being a GN nut, the bulk of my engines are MTH as they are the only ones that have made any scale GN steam/electrics. The M-2 is my first TMCC engine. I've got a NP Z-5 coming in a week, or so, and I'll see if she smokes well or if that's the nature of TMCC smoke units. My MTH GN Z-6, R-2 and S-2 smoke like the full size engines.
Thanks, though, as that does give me the idea of emailing Scott and checking if he has any suggestions.
