Thanks Lofty, I think that is a very clever spec - not loaded with depreciating features.
However, it's probably missing just one or two creature comforts for me - so I'll pass and continue with my build. Good luck, I'm sure you'll have no trouble shifting it.
If anyone is trading in a super spec'd SD please give me a shout by the way - it's currently an option I'm exploring (I have a GTS on order in the meantime though...)
