Careful with a new inductor. Lower DCR, from the stock 0.4ohms will change the crossover frequency. Personally, I'd not do that without more knowledge.
Someone out there with simulation software or who can 'do the math' may want to comment on this.
That being said, the main advantage of an aircore are 2x. Higher current capacity and it won't saturate at higher powers.
Also, if you consult some of the inductor design calculators, you can design an inductor with the same number of layers as turns per layer. This makes a perfect 'square' cross section inductor. Going thru several iterations, I managed to get to 0.38ohms using 13ga wire....If I remember correctly. This is the one I'd build or have built. Pot it in epoxy and give it a couple hours in the oven and you should be golden. I preheat to the lowest temp, shut it off and let it be. I did something similar to slot car armatures back in the day.
