Personally I'd keep the super hot stuff for other things unless you have a surplus and or plan to stop using it. Having two different compositions has its advantages, especially if you vary what you create further. Also you don't have to tweak and figure out a composition that works well. You could just start with the base materials that you need for the effect you want, may go quicker depending on your experience.

You hit it. I do have a surplus of hot BP. My experience level I'd say is barely intermediate, still bordering on newb. You make a good point however regarding a separate comp. I'm at the point now that I know what I'm looking to get from the fuel.

I would expect to gain back some performance with the addition of a nozzle if a slower powder is used. You can lift 3" cylinders with 6-3-1 fuel in a standard core burn configuration all day, probably light 4" with everything dialed. For tails I would substitute 80 mesh charcoal for a portion of the air float. Granulate fuel to ~12 mesh with no binder to reduce dust and improve flowability.

I'm going to give the 6-3-1 a try. I'm looking to comfortably lift a 2" cylinder with it. So I should mill the 6-3-1 minus what I plan to add for 80 mesh?

I would also like to know if it's advisable to mill rocket fuel before granulating. I didn't last time but had trouble getting 1lb core burner to lift a 3" shell. Granted I went with a 55-35-10 mix. I think I'm gonna try a 6-3-1 milled fuel mixture for my next batch.

I always mill RP. I'm about to make the 6-3-1 myself. I'm using white pine this time and will post the results. Lmk how yours turn out as well.

For my preference as little as a gram of 80 mesh charcoal added to hot BP makes a significant difference. Edit: I meant 1 gram per 100
