As you may have guessed I made my mind up not to do this flight before I posted the thread, reason being that the freezing level was not really compatible with an airways flight and the low level option is just a bit too complicated plus as many have said would have made for a rather bumpy flight. I'm sitting in a service station right now near Carlisle and the cloud is very low indeed, something that one should tend to avoid when flying a single in IMC if possible.
Thanks for everyone's thoughts though...and do keep them coming.
