I think you need to be a bit clearer about what you actually learn via Heisig - it's not accurate to say you're learning the meaning of kanji (which have several meanings depending on how they're compounded or not with other kanji), which you're not actually. And my understanding was that you don't learn the readings either. I could be wrong on that but learning all the readings for a kanji is a terrible approach. Much better to learn them by way of learning vocabulary.
Heisig seems to be best as a way just to get all the kanji into your mind as opaque artifacts, just a visual familiarity primarily. Which can be a huge help when you actually start learning Japanese.
