any > 0.7mm pick will do for me.
for most durable pick,
u can try chrome metal pick from S&B, but it will damage ur guitar strings...

now using jim dunlop tortex pick, the material seem like more durable compare to other plastic/fibre pick...

ohya, i do collect ESP artist picks for fun... =)

I got those ESP picks from one of the small Kuching guitar store, when the taukey masuk angin ordered 1 packet of ESP picks from singapore's Davis.

It's not cheap ohh... i got it for RM3.0 each....
(note: jim dunlop tortex only cost me RM1.0 each in the same shop...)
