Recently I enchanted my new diamond pic with a 30 level enchantment and I got this: Efficiency 4, Unbreaking 3, and Fortune 3. It is an amazing pic! Mines dirt instantly, stone very quickly, and best of all I can get up to 4 diamonds from one ore! Using this pic I got about 50 diamonds very quickly from a branch mine.
What awesome, amazing enchantments have you gotten?
You should be struck down by the minecraft gods for such sacrilege
Seriously though, IV Efficiency on a shovel is better for dirt or sand collecting, plus you're using less diamonds to make it each time it breaks (1 diamond for a shovel versus 3 for a pick)
As far as cool enchantments, I actually have 3 picks with Efficiency IV, Unbreaking III, and Silk Touch. I've been hoarding them for some reason, but I think with 3 of them, I can finally take the plunge and use one of them.
With my luck, I'll probably fall in lava immediately after taking it out of the chest.
Oh, and I have one of these. They're not the best in the game, but I hope it'll speed up my wither skull hunting:
