Happy Friday Folks! I am looking for a low diffusion rig and I see that Grav Labs now makes the Bates/Worm for much cheaper and is interested in picking one up. Just not too sure which one would provide better taste, the internal or external. External almost looks like a recycler which has me leaning towards the internal. Anyone own both rigs or have used both? Your feedback would be greatly appreciated! I plan on using a Flowerpot with this rig.
