One thing that I'll add to my earlier comments is that a lot of the experimentation I've done in my system and the knowledge I've acquired is a direct result of getting to know other enthusiasts and picking their brains and finding some people to mentor me.
Join a local club if you can and then get to know the members that seem to really know their stuff on an individual level and spend time listening together. Listen to their systems. Ask a lot of "how" and "why" questions. Invite them to listen to your system, and ask for honest feedback.
