Particularly resistant? Really?

I really like to play these picks ...
because I get slightly sweaty hands and there is this grip surface very helpful
the only shortcoming of the picks is the shelf life ...
wear out quite fast ...

I buy it because I still fits the shape well
(Not as sharp as the Sharpy pleks of Dunlop, but not as round as the very long-lasting Tortex pleks (also Dunlop))

But the Apply these "high resistance" is just bullshit
written or by someone who misunderstands the imprint Heavy.
Heavy referred of course the thickness of Pleks which are also classified in terms of sound, the direction Heavy)

Medium I would basically do not buy because they wear out much faster still
the greater flexibility can be advantageous.
