I played Tortex sharp 1.14mm for years. Some months ago I thought I’d try some different picks to see if there is some improvement/change in my picking technique.
I can definitely recommend to try different picks AND keep practicing with different picks from time to time. If your stuck with one exercise, just take a different pick for some minutes, sometimes helps me to break some kind of a “day-barrier” (meaning I can’t get some exercise up to speeds I usually manage to play).
So at the moment my main Picks are Ultex Jazz III XL. They play a bit easier than the Tortex sharps, because the tip is pointy, but not as pointy as the sharp picks. For faster stuff I sometimes change to the red Jazz III XL-picks (Is that Nylon?), because they have a more crisp attack, so fast stuff on the lower strings is a bit more precise (tone-wise). Still I like the smoothness of the Ultex on higher strings.
I tried the black Jazz III-Max Grips and keep using them from time to time. I think they are to small for my large hands, but this really stirs up my playing in practice sessions, when I feel stuck.
Funny thing is, that I somtimes feel like going back to the Tortex sharps and might do that someday, when I reached my “alternate-picking-goals”. (To be honest that will never be the case, as my goal is “faster-faster-faster”
Just my 2 cents about Picks…
