Tim, I do like them too. Especially the no oring part. But I found that on the chalice they did not offer any advantage because of the smaller hole in the top of the chalices cap beneath the drip tip is the limiting factor.
But the difference on a cyclone is noticeable because the hole for the drip tip goes all the way thru.
Strangely I do like the feel of these tips though.
Even thought the chalice has the condensation catcher hole I've found they do provide a different draw compared to my old drip tips. Guess it makes sense because in theory anything bigger than the air hole should not make a difference but it does for some reason.
I really like the feel of them too, and they fit super tight.
