Good post CC,
I have found the same thing about using large lava rocks in the bottom of my containers or even geolite, they house the microherd nicely.
It had never once occured to me that composting could make the perlite better though, that's a cool plus to recycling soil.
It's also a factor since perlite doesn't get used up in a grow, thus recycling the soil mix has to factor this in, you can't keep adding 30% perlite every remix.
