As I said earlier in this thread the trouble with LL, and especially in the C130, is the extended planning cycle on JAMPA and then only half the time is spent hand flying, the other half reading the map.
Now, when I was in the Falklands we transited everywhere at LL, free Nav with no planning - that was fun flying - but it was over 25 years ago, when some of the posters on this thread were actually still in the RAF...!
