More 6 CR?
As people will have seen in various magazines the MK 6 CR has proven itself to be a very capable helicopter. The things that it does miss (DAS and some more seats for example) could easily be read across from the Mk 4 if they were required.
As for the future - there are thoughts out there, but that is all. It could easily fill in for Puma until we have a SK4 / Puma replacement - which would mean no extra Junglie Sqn, but an RAF MK 6 CR Squadron.
However IMHO the RAF will not find the potential loss of Puma too attractive and therefore (in line with Jungly) logic, cost effectiveness and capabilty will not win through.
