If money's not a problem what's the best oil rig for taste, smoothness, and content lost.
Well thats kind of subjective as smoothness and taste often require less of one and more of the other..what i mean is generally a "smooth" rig usually isn't as tasty as a rig with lesser diffusion. And obviously more diffusion equals more reclaim, or contents lost as you said. So it really depends on your personal preference and what matters most to you.
If you are most concerned with taste and lack of lost errl; a simple two or three hole rig would be the most economical option. Beer glass is a good choice if you can find one. Or van tran makes some quality, affordable rigs. If smoothness is the priority i suggest something gridded. Sov, cycler, some kind of gridded showerhead bub, dg fritted disk. But be warned, heavy diffusion kills/diludes the taste of bomb oil, and the amount of reclaim will be significantly higher.
As for a middle option, a closer balance of flavor and smoothness, i'd suggest like a b. wilson 6 arm, or some other sci. bubb with medium diffusion.
