Thanks for the comments and thoughts...
highwinger - let me know how Elstree looks will you?
BlueRobin - nice line, but does it mean?
I'm hoping that one will come with the other as long as I'm doing different stuff.
DG - like the thought of being based at two locations, so can go North and South easily - would be nice to fly near the coast.
I think I'll definitely try to get rated on a PA28 as it will increase the options open to me.
