As Light Dude said, Bestine is a VERY selective solvent, so if you only pull with it, you'll be leaving a LOT of goodies in the mix, which isn't very good practice IMO.

After you do your initial pulls with bestine, you'll want to follow it up with either some d-limo pulls (for food safe) or xylene or toulene.

Good luck with your extraction and Welcome to the Nexus!
