As of right now have been using plain old Fender Celluloid pick's 351's, gauges vary depending on what I'm up too, and what guitar. However it always seems to between a medium or a heavy.
Still have some Red Bears and other boutique company's, have not tried them all: but allot! Truth of it, they all have good point's and still use them from time to time. Especially on acoustics this is were the differences shine.
Others,
Intune guitar picks. Prices vary depending on what you want. The shapes are pretty much standard and it's a little more about the graphics.
I got mine with the material Delrin, really like it allot and the picks are just made well the bevels are consistent from pick to pick. Graphics are fine but it was the material and shapes that attracted me to Intune.
Like the Dunlop Ultex also.
I always seem to come back to the Fender celluloid, there was a time hadn't touched one in five plus years but still came back to it.
It's not that they sound so much better, make me play better, or anything like that , they just "feel right"
