Real life performance will be around 232-235kB/s due to the synch rate on 2Mbit being less than half that of 1Mbit (1MBit synch rate downstream 1152kbit, 2Mbit synch rate 2272kbit)

There is no 'trade off' made at all, one can't swap upstream speed for downstream speed. Upstream speed on the BT RADSL 512k service is reduced if the line is too close to failing due to poor signal to noise ratio, the downstream signal takes up some space occupied by the upstream to keep the line up. You CANNOT swap upstream for a higher downstream, all BT ADSL products are locked at your max downstream.
