Hey Joel,
Sounds like you are where I was around 18 months ago. The synthetics we have access to are possibly less of a challenge.
Part of the allure of naturals is that they require trial and error to learn how to achieve the desired results.
Some of us enjoy the process.
I have been exclusively using my trans ark this last year and a half. Have found what works for me with it. Haven't felt the urge to get a different rock as of yet. But if the right deal comes along I will prolly get another natural to play with.
At the lip of the rabbit hole I would say.
Ken
