    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.

    Just picked up an internal (though china glass) planning on using it with my E-Nano. I will let you know how it works out.

    mrbonsai420 I love Grass and Glass!

    I have both, Both Grav labs not China and they are both sweet! I think I like the form factor and function of the internal better, BUT I use the external more because it looks cool! That being said I have so many new, colored art rigs I almost never use any of my scientific glass :( It's been a long time since I have pulled those out!

    I have a Bates external and a Grav Labs internal. I like the extra height of the external, so it's my daily driver. The height does make it feel a little more tip prone and I worry about it. I also like that it tends to stay a bit cleaner. My external also has a vertical joint, so it's a lot easier to get things lined up compared to the Grav version external.

    Wow, me too....Bates original external with vertical joint (which wasn't easy to find, by the by) and Gravlabs for the internal.

    I rather agree that I like the external more....except it needs a wider/heavier base, IMO. I use a Liger banger and that sucker is heavy. I needed to get drop downs that kept the Liger very close the the vertical tube, otherwise its too liable to tip. But I love the function, performance, taste.

    With a torch nail or even perhaps a D-nail slim line Halo, it may not be as much of an issue.
