When do you replace your pick?

[mainestratman]

I use the Tortex .88, which never seem to wear down *too* much... of course, I lose picks like you wouldn't believe. Some I put "someplace safe", never to be seen again... most I lose when I throw it at my drummer for daydreaming while I'm trying to end a song. :-)

Depends on the type of pick. If it's one of those celluloid ones, they get shaved off pretty quickly, so it's either when they're too rounded or when they actually shatter (this has only happened a couple of times).

I just started using Tortex and they seem to hold up better, but I imagine it would be something similar like being worn down and becoming too rounded and thin.
