On my journey to find the best pick for my personal preferences I've gone from bigger picks (Dunlop Tortex) to the Tortex Jazz III XL, before discovering the original Jazz III's for myself.
It did take me some time to fall in love with the Jazz III's, but I can't go back anymore.
The thickness is nice and their texture allows for a good grip, while not being "glued" between your fingers, so you have all the flexibility you could ask for.
They also have the perfect size so that I can always hit the strings I want, and the small nature of them makes it easier to play faster than with "normal" size picks.
Definitely give these a try, if you have not already.
