I would interested to know what you are after in your choice of posting?
And what is your rational behind Ks 1st
Js 2nd.
You asked for views from own types only however I will give you my penniesworth anyway.
C130K
good variety of roles, some very demanding, can be difficult to pole at times
AT role not as demanding, slow speed of aircraft can at times make up for lack of capacity
C130J
gucci kit, handles similar but better than K, 2 pilot cockpit means no room for slow developers
computer literacy a must.
will in time assume C130Ks demanding roles.
Sentry
Can be a pig to fly at times, good dets.
Nimrod
Good role, demanding flying, good area, bad location (distance from rest of world)
125/146
Few slots, good role, good station and a sqn from the halcion days.
125 more demanding than 146
146 flies at J speeds and heights not hard to fly but lot involved in operation and potential for captaincy on type expected
VC10
Fast but not that demanding a pole. AAR role demands good capacity.
TriStar
Bags of flying, AAR adds variety. Aircraft not as hard as was made out, but 3 man flight deck means no passengers in the RHS
