It must seem like your clothes will go out of style, or spring will come maybe, before he gets your stove install completely dialed in !
Glad you're up and burning at least, and that you found some good pellets to burn. It seems most of that comes down to trial and error of what burns best in your stove setup, and your desired level of heat output vs tolerable level of cleaning required. I agree with Pellet-king, as cold as it is in the East this week, I'd be burnin' those Oakie DF's in a heartbeat !
I learned not to trust the premium / super premium / platinum ratings that pellet manufacturers grade their pellets as when I burned what were rated as premium pellets my first year of pellet stove ownership, that ended up being literally dirt in a bag. They must have included the dirty bark, leaves, branches, etc in their source sawdust - horrible clinkers, door glass was black after burning the first bag, poor heat output, creosote everywhere in the fire box, etc. The particular brand will remain nameless to 'protect the guilty', but I will say they have improved markedly since that first production year.
The Pellet Fuels Institute does not have exclusive rights to the word “Premium”, so if you see a brand labeled as a “Premium” fuel but it doesn't have the PFI logo on the bag, it's unlikely that the manufacturer is even testing to the same standard.
I don't believe there is any functional industry standard on what constitutes one pellet grade from another, and that it is more about market branding and product promotion than it is a usable pellet quality indicator. Just my .02, FWIIW.
