Thanks ro all for the tips. In the end I bought a selection of VFR+GPS charts and trip kits for Germany and France.
So far my observation on the trip kits is that they are very detailed, the only criticism being the lack of data on fees and the sheer weight. A rought idea, even if out-of-date, of whether landing will cost me 10 or 100 EUR would be useful, and I'd be happy to loose the area charts in favour of a drop in weight - nevertheless I do like to format of the area charts.
Unfortunately weather has so delayed my plans and had to stay on the ground today. Hopefully tomorrow will be a better day.
Thanks again.
