Podocarpus Macrophyllus - Soil Suggestions

Does anyone have a soil recommendation for podocarpus macrophyllus? I recently acquired a large specimen and am planning to repot this spring with akadama and pumice. Wondering if others have had success with that mix, or something else. Thanks in advance for the advice!

Here is a bonsai citation…

Not a tree I would tackle. Good luck.

I saw the Bonsai Empire guide, but it is pretty limited. This group out of Germany seems to have a better care guide (Buddhist pine bonsai care). This particular tree seems less popular outside of China, so not a ton out there.
