Yep, Andy wheals is good, a lot of people recommend him.
I've used David Sayers at yarm and although some people dissed him I found him very experienced and he found a jumping saddle to fit my unfittable wide, flat backed pony. The pony had a bad back when we got him from a badly fitting saddle but now he's fine.
I have just had Cicely Jeffrey from the national saddle centre who did probably the best job I have ever seen on my very hard to fit pony. She spent 2 hours watching my daughter ride, restuffed and reshaped until it was a perfect fit. I was also left a copy of his template with the comments filled in as to what was found and work that was done.Also there was no massive waiting list as her area is the north east. Hope that might help out others looking for decent saddle fitters in the area.
