Best Picks for Bass Guitar?

"Best?" I hear you ask with a raised eyebrow, lifting a finger to prepare an objection. 

"Well, I mean, I haven't really tried all that many different picks and I'm not even a great bass player to begin with, plus I'm restricting the search to affordable picks because paying $20 for a hand-shaped glass pick that I'll lose in five minutes just doesn't strike me as sensible, but these heavy Clayton acetyl picks work pretty well compared to the couple of other things I've tried in my day."

Your raised finger lowers, signaling that you've decided a counter-argument isn't really worth the effort of raising after all, and accept the lukewarm, unsolicited product recommendation with a small pile of salt.
