Max;
I'd strongly suggest taking someone more experienced with you first time if you can, I think AlanM would concur with that one. The LHR/LCY zones are not a good place for DIY instruction. Also don't forget that if you are going into Battersea you need a dual check and briefing from ATC on arrival. Chances are however that you already know the zone from flying singles/mil around it in which case all of the above is totally irrelevant!
