Oh difficult choice for the top 2 but at the moment an possibly only because I know the lines better I'll have my list as:

01) The Girl In The Fireplace
02) The Time Of Angels
03) The Sontaran Stratagem
04) Aliens Of London
05) Daleks In Manhattan

just giving this a nudge in case there are any last minute voters out there...

oooh, 26 minutes left.

Get your votes in now peeps!
