MM, I would say, experiment with as many different styles of finger pick as you can afford to try. A lot of people find that one brand or style works best for them but there's no way to know what works for you without trying them.For my zither and zither-harp I'm currently using: brass picks for the right hand fingers (they give a soft sweet sound and minimize clicking); a regular plastic thumb pick on the right hand; and some funny, rounded, downcurved plastic picks (that can't catch the strings) on the left thumb, which needs to strum chords right-to-left on the zither-harp.
I don't like to use these rounded "backwards" picks on my right hand because the sound is too muted and I use the right hand to pick out the tune.
There are picks with a "point" at the tip, which I like sometimes. In my case I need the pick to be as similar as possible to the "feel" of picking with my nails. And it mustn't extend far enough to catch the string if I move back down the strings too fast and don't lift my fingers quite enough. I'm starting to try sitar picks because they can't catch on the strings as I move from string to string. Not too good for guitar, though.
I'm sure you're going to get an awful lot of opinions on this!
