* Vector the 2nd aircraft (at high level) to achieve the 10NM and then give him profile speed on the drop?
That sounds like the best option to me - a little correction a long way out and then a nice efficient descent - at least until we get dicked around close in
* 2nd aircraft to min clean in the cruise, and not abv 250k on the drop?
Do that and we'll have the speed brake out on descent (almost all the way down) unless you give us reasonable warning so we can program that and start descent further out.
* Leave on profile in cruise, not abv 250k on drop and then vector at about 50NM to achieve the 10NM spacing if I don't already have it?
That seems to be what usually happens
* (Prob the most preferable...?) but give the 2nd aircraft a time and speed to cross a feeder fix at 50NM a while out?
That works but often we don't get told until we almost can't slow down enough to comply.
In the end the best laid plans of mice and men do oft go astray
