Different Picks maybe?

[ViperZakuto]

What does the gk community think about having different picks for mining?

my idea was to have 3 different picks

Pickaxe
Gold Pickaxe
Mithril Pickaxe

now the regular pickaxe takes about 29-39 hits to break a rock. Maybe make the gold pick should take out the rocks in say 22-32 times. The mithril pick would take it out in like 17-27 hits? it's just an idea.

would this be too hard to script?
