Card dilemma

[jromie93]

I just got a new Nikon D7000, and am due for a new memory card. I am looking at two that fit my budget. A SanDisk 16GB SDHC 133x speed for $57-ish; and a SanDisk 8GB SDHC 200x speed for $42. I am really wanting some extra space but with a 6 FPS frame rate, is 133x fast enough? Or is 8GB plenty of memory? I shoot a mixture of action and long-exposure landscapes. My camera's NEF (RAW) images are around 17-19 megabytes each. Please help me make the decision! Thanks!
