Gonzo its common sense never mind Airmanship.
Also its normal to have 2-3 cunning plans for fuel managment as well.
All goes wel,l get the transits no need for a fuel stop.
Bit more head wind than expected fuel stop at egxx
Don't get the transit sod it when can get some lunch and fuel at egyy.
Although to be honest the pilots that seem to have the fore though to do as you say are usually the ones that have enough savy to hoof it on the fly and go with the flow with only a loose plan with 3-4 different options. Mind you these pilots are the ones that are more than likey to get zone transits cause they not only know what they are doing but also sound like they know what they are doing, so get the transit.
