Interesting how many Jazz III's there are here. Good for lead work for me, but lousy at rhythm (my technique I guess sux there.)
I've done quite a bit of moving around with picks. Tried pretty much them all. My absolute favorite are Red Bear...but at $20 a pick (and generally a waiting list), I gave up and put my RB collection into olive oil to keep them healthy.
My go-to's are Fender heavy's (the purple moto ones...I know it makes no sense, but for some reason those ones feel and sound 'right' to me...I've tried the red in that same style, and they seem different.) I use Medium's for acoustic work. I'm a bit anal about it, and the 'Fender' logo has to be pointed up at me.
In the end, I can get 4 or 5 million of them for $20, and they are literally everywhere in my house.
Oh, and they sound great to me.
