For years I use Fender Heavy Glo picks (yes, they are phosphorized and glow in the dark, at least a litte bit of RNR for a man my age).
The reason for playing this sort of pick is that while I was working for Fender I picked a bag of these picks and I guess there were about 500 of them in it, so I still got enough stock. I fear the time though when the bag is empty.
I only use very heavy picks.
