Should work for all of them.

511 works, but you'll get more time in grit.

If weight is a concern, could incorporate pumice, but keep in mind that pumice can be rather alkaline, and really unstable, soft. Bonsai Jack sells hard stable pumice, though typically a bit high in pH. Hess is in the western U.S., and theirs is hard, pure, and nearly neutral pH.

For increased water availability, could use some calcined DE. I've seen the NAPA product turn to mush, though. I've been using Axis regular, but the waste factor is just over 50%.

I find runoff water from calcined clay, which came out of the tap at 8.0-8.3, can be 4.0-4.5. Calcined DE runs 5.2-5.5. Pumice tends to be more alkaline, as high as 8.5 or more.

I have plants in gritty that combines Turface and pumice, and after several months, the runoff pH is pretty balanced - what comes out is pretty much the pH that goes in.

HTH.
