Eleanor Halley at Saddleworld is really good, very thorough and knowledgeable.
i'd highly recommend her, She's fitted lots of saddles on my yard and we're all really happy
Alex McCracken - brilliant, he knows what he's talking about, and he rides (events) so when you explain to him what you need/feel/hate/love he will actually understands
he will re-flock/adjust there and then and if you need a tree adjustment he does a really quick turnaround!
