Gotta B Jepp
If I'm going long distance in Europe it is (nearly) always IFR - it is just so much more straightforward. I use:
Jeppesen Flitestar IFR with integrated weather - for routings
Jeppview CDs for current approach plates - print them out the evening before (beats the hell out of dealing with the paper revisions)
(VFR in the UK I use AFE VFR guide and the 1:500000 charts.)
