In reply to petestack:
I've been out with several guides and MIC's. Both on courses and as a private client. As someone said all in my experience will give you a great day out. All mine were. And I would rebook with all. Some you will click with more personally etc.
The best in my opinion have been Andy Cunningham and Dave Etherington.
Alan Kimber's set up you can't fault and I would start there.
One thing to bear in mind though, often when you book with established names, you may well go out with an associate or another member of their team, depending on diary commitments and your aspirations for the day.
