Lifted from the DS forum this nugget :-
"" Whether the twins are near identical or not is only part of the story as the birds won't be in exactly the same position, nor will they have exactly the same attitude. That's of no consequence for the target consumers, but will inevitably mean that the sharp lobes and nulls will not coincide withose presented by 2F, so fringe punters may get some interesting results depending upon how the Channels ultimately get distributed across 2E and 2F ""
