I just got an ebony sarod pick from Michael, and I immediately discovered that it has one major advantage over the other picks I've used (besides price): NO PICK ROTATION! That's because it has a curved groove on the bottom for the index finger. This allows it to really lock into place.
The pick is just a little longer than the Wegen Twin and the same thickness from what I can tell. It sounds great so far on my Collins petit bouche; on the wound strings in particular it produces a warm, dark tone. On the high strings it sounds much like the Wegen. At such a low price ($3), this is definitely worth checking out. I'm going to try the rosewood one too.
Allow me to repeat: NO PICK ROTATION :!:
