thanks - i suspect that you are right....
I'm actually using this as a mouthpiece for my SSV and I'm finding that the hits are wider and more pronounced. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=380756389010
I feel that not enough has been said about the significance of mouthpieces beyond the aesthetic. A change in mouthpieces has in my experience transformed the vaporizing experience.
Thanks I have been looking for those! This is the best mouthpiece I have found for Herbie whip. I picked up one at a head shop(do they still call it that?) or smoke shop. They didn't know what it was and sold it to me for $3.
