How about
:
[your route to] BKY DCT DET DCT DVR B3 VATRI G40 ARSIL A6 DJL DCT
(which passes IFPUV with DCT GOLES DCT BKY)?
Oh damn it Donks, you've replied too. We're going to have to coordinate our route planning services.
For the UK part, I agree with Donks but if you don't fancy ducking under the TMA I'd suggest a join north of Stansted at FL70 or FL90. That has worked for me before -- I think it was Marham that got me the handover to London.
