Yep, I run mine at 216. I just use it for credit runs between two systems, and don't often get interdicted, but I like to keep my shields to give me SOME chance of escape if I do. That cargo space gives me 290k profit one way, and 77k on the way back. Good enough for me and on the balance of things I value the little bit of security the shields give me compared to an extra 16 tonnes of cargo capacity.
