Gentlemen, thank you so much for your input, all of which is very helpful indeed. I was all up for changing my mind and realizing that a share of an aircraft as long as there were not too many people in the group looks like it makes more sense until I got to silvaires comment which suggests why does it have to make sense, after all it is fun and so what if its a silly decision?
I guess the thing for me is probably to try the shared ownership route for a few years and see how I get on, if I fly enough that I could warrant owning my own aircraft I am sure I can over time convert to that.
Very helpful advice thanks indeed
