I'd throw 5GH/s at a pool that paid out in silver/gold/commodities. Frankly, I find the entire process of buying commodities via Bitcoin to be awkward and weird, and would much rather just be sent a silver coin or a gold coin every X amount of BTC.

I'm unique, though, and others might not feel that way. But it'd be a unique, easy, straightforward way to "hedge my bets" with the BTC I'm churning out.
