IME no matter the tek, or bark used; If heptane is the initial nps, it will pull a cleaner product. However, Bc it is harder to find/more expensive, it seems as though using naphtha is recommended for the simple fact that its readily available everywhere.
Conclusion; Pull with naphtha, and clean with heptane.
Unless you have a steady supply of course, but you'd be missing out on all the other active "mystery" alkaloids that the various source material have to offer.
I'm still learning about Jungle Spice and methods to pull it from "spent" basic bark soup. Just hesitant to use harsher solvents. It doesn't seem worth the hassle required for the remaining "extraneous alkaloids" that make up Jungle Spice
is it worth it?
