Managing finger/thumbpicks is as personal as choosing the most comfortable shoes. And, to drop the comparison, it can take as long to make your own adjustments as it does to learn any subtle skill. I've played with my fingers since I started back in the 1950s and discarded every style and size of fingerpicks I tried--they all changed the right-hand geometry too much, even when they didn't fly off my fingers. (I have a boxful of failed experiments somewhere.) But I still wanted the option of a strong bass line, especially for thumbpicking style, and I eventually discovered that the Herco plastic thumbpicks 1) don't strangle my thumb and 2) can be trimmed down to minimize how much I have to change my right-hand attack.
I shorten, round, and smooth the point of a Herco medium (nail clippers and an emery board) so that about a quarter-inch protrudes--it's just enough to engage the strings without having to change my right-hand angle a lot, and it sharpens the attack and increases the volume of an alternating bassline. I keep my fingernails just long enough for flesh-and-nails playing, and it's easy to revert to playing without the thumbpick as needed.
