Jonnyloove - there will inevitably be a mix of aircraft - I think most bidders will have 2 types in their fleet, one for long range/big lift and another for short range/coastal work. The Interim CG contract is using S92 and AB139 but there are all sorts of other combinations that may be offered, including 101s.
As for impartiality in SAR H, you would have to start the whole process over again and achieve nothing by doing it. Whatever the best theoretical solution is, the actual result will be driven by politics.
SARREMF - yes I was there and yes, my head did hurt the next day
