I've been using these for a couple of years with my Precision and Mustang basses. With these you really get that powerful P-bass pick sound. The green one 0,88 just feels right for me, not too thin and not too thick.
A 72-pack would last me forever, except for just one thing. The grip kind of wears out slowly, but still faster than I would otherwise have to change a pick. This is a minor gripe though, the 72-pack is cheap and lasts for a very long time.
For gigging I just make sure that I have one or two fresh ones and I'll know they won't slip in my fingers. I only gig a couple of times a year, I'm just a hobbyist, so I don't need fresh ones all the time... So for me these picks are almost perfect.
