I'm not keen, wasn't happy with saddles I've seen him fit so I'd go elsewhere. The only saddle fitters in East Anglia who I would touch with a bargepole are Liz Leggett and Alison Braithwaite from mill saddlery.
I have not heard great things - only personal experience i have had is many years ago but was not that impressed. I would go for Mill Saddlery at Stowmarket as well.
