Any thoughts on how to approach would be very helpful.

My understanding is that you don't want to take heat away from the combustion chamber as that needs to be as hot as possible to burn all the combustibles but after that adding mass should not affect the draft.
If you're seeing some smoke past the initial burn that suggests that your fire isn't as hot as it could be ... unless you're actually still seeing moisture being driven out
