TBH you dont want the upgrade.. as soon as you get 20mbit you will start to be traffic shaped if you download more than 3 gig between 4pm and 12am
Your correct, traffic managed would be more appropriate.. still sucks that the XL package gets a 75% reduction in speed but the lower packages only get a 50% reduction.
And on the 2mbit isnt its a 350mb limit then your dropped to 1mbit .. you can hit that just by browsing f**king youtube or somthing..
Been looking into bethere.co.uk but means i'll need to change back from telewest phone line to BT
