I just got a 1.5mm Dunlop Flow pick, and I like the design a lot. The sizes are 0.73mm, 0.88mm, 1.0mm, 1.5mm (what I have), 2.0mm, and 3.0mm.
I find the 1.5mm to be totally rigid (if I try to bend it with my hands), so why do John Petrucci and Andy James both endorse 2.0mm? Why does Dunlop even offer 3.0mm? (Or, rather, what leads a customer to want a 3.0mm thick pick when the 1.5mm seems to be totally rigid?)
And if somebody has the 1.0mm version, do you think it is “totally rigid,” or somewhat flexible?
