Yeah, I went browsing all the different AFC driptips after I posted that, and came to same conclusion, that they won't help, that I really need a driptip with a very small hole. I did try a kayfun driptip, TD, and that worked pretty well, but.. I just can't stand the way those look, they remind me of baby-bottle nipples.I'm thinking of getting another "genie" driptip for it, a black one, because that one really does have a small opening, and they're also pretty dang tall, so that gives me some distance from the hot coil. I think that may be my best solution.
Can't figure out why everyone was saying the Derringer has "restricted" air flow if you use just one hole... it's not true; I've got the barest edge of just one hole showing, and I can't feel any resistance in the draw AT ALL, just none, it's like trying to "smoke a straw."I'm really disappointed. So far, of RDAs, only the Magma seems really suited to tootling. I find the Veritas a *little* too airy, even with the barest edge of airhole showing, but I think it might also be helped with a driptip that has a skinny hole. But I like the Magma's architecture the best; with an o-ring under the AFC ring, you can remove the threaded cap without disturbing the AFC setting, and that is TERRIFIC. With the others, you have to readjust the AFC everytime you take the cap off, and it's a pain. Think I'll just get another Magma, maybe a black one this time.

Most adjustable driptips are carburetor style, allowing you to mix air with the vape from your atomizer. Most vapers looking for AFC drip tips are looking to increase airflow for atomizers like the KFL.
What you want is a restricted driptip that uses a Kayfun-style adjustment, like this:

I also remember seeing driptips with interchangeable diaphragms. But they were rather large on the OD.
ETA: If you are handy or have a handy friend, pick up a metal drip tip that can be drilled & tapped. Insert a thumb screw and you have an easily adjustable restricting drip tip.
