My personal approach, if I had $10000 land in my lap, would be one of two options:

1. Wait until a more reputable ASIC vendor (read: KnCMiner, but up for debate) begins accepting preorders for their next generation of ASIC mining hardware, verify the stated hashrate will net you a positive ROI, and place your order as fast as possible. Usually, the farther from the front of the line you are, the less you'll profit.

2. Put your BTC into multiple exchange accounts, open a CryptoTrader Pro account, and let it manage the day-to-day trading for you.
