I recently got me a couple of Teflon drip tips and I love them. They are really slick and have not had any mouth crud deposits on them after several weeks of daily use. So my question is do any of you have a good place with an excellent selection of Teflon drip tips? They have to be 510 because I don’t use 810’s at all. I much prefer the smaller hole and the restrictive airflow I get from a 510. I’ve never gotten acclimated to the 810’s , they are just wrong. So I need a source for some vase or some variation of the vase in 510 made of Teflon. If you haven’t had the pleasure of using a Teflon drip tip I suggest you keep an eye on this thread and get yourself one, it will not disappoint. Thanks in advance to any contributions you can provide me.
