I would agree with TKF. This is exactll what I did and it works a treat.
However, I did get a bit carried away and found myself doing all sorts of cross countries during the working day and was concerned that I was becoming slightly obsessed! (Voices in head and all that!)
It came to a head when I found myself at a particularly boring dinner party one night and ended up silently "RTing" from Blackbushe to Sandown. The other guests were wondering why I was ignoring them but I seem to recall it was a good flight!!
I think I'm ok now although I have this strange desire to fly under bridges these days but that's another story.....
