Yeah I don't know if anyone else near me! But I'm about to move all them to Texas! Might find some people down there!
So I use a mix mostly comprised of red lava rock. Maybe 80% and 20% peat/perl mix. 90/10-95/5 for P. brevicaule.
I was a bonsai apprentice in PA for 5 yrs and grew in pure stone, so I lean that way with with these caudiciforms too. It's worked extremely well for me. You have to Water a little more frequently with this mix of mine but root rot problems never occur now, I feel like that's the biggest killers of pachyies is root rot. They get small amounts of water more frequently, but the soil never gets too wet and stays wet for any length of time. This has led to a better increase in growth and development of caudices.
You mentioned you had a problem with P. saundersii being too wet in your area. You might want to try switching to a mostly porous rock mix.
