OK - I can see you're all fed up of my rantings.
Have absorbed advice from you all and made my purchase. Picking it up tomorrow.
Have gone for an AA 400 Superlite - with the money saved will spend more on some nice glass and see what I can hit.
If the Superlite delivers in my hands I have the option for a custom stock - am making a few a enquiries over the next few days to see what I would need to spend and with whom to get something interesting.
Thanks for all your input.
