For MTL I like the black plastic/delrin style drip tips that come as spares with Berserker tanks.
For dual coil RDAs that use 810s I normally swap the drip tips for the type used on the single coil Recurve 24. They look pretty stupid on most tanks but they are really comfortable.
Bought a couple over the weekend because they looked bob on. And they are, I love them. But agree that the connector is a tiny bit too long, and also find it a tiny bit too loose. I like a decent connection so that I can pick the mod up by holding the drip tip. Any looser than that and I will lose it coming out of a pocket or something.
