Thanks for the tips.

you are creating a much higher workload for all concerned. It is also the route followed by most of the EBBR departures to the west and they will be climbing all the way against you.
That's understood, but there doesn't appear to be a problem with flying that exact route and
overflying Brussels at, say FL90. That's permitted by the RAD. Only if my destination is
in the Brussels TMA is it prohibited. Since I'm going to be at FL90 at COA in either case, it seems odd to permit the route for overflights but not Antwerp arrivals -- Antwerp has no STARs by the way. The alternative, permitted route also goes through NIK.
