I think r an r country are meant to be good, and I think rideaway also come out don't they? My friend had RandR to fit her horse, and they brought lots of saddles with them - new and secondhand - although took her 6 weeks to get the appointment. I'm not sure if Mrs Fraser at Beckwithshaw comes out, but she does do saddle fitting at her beavers shop.
Think the guys at Fox saddlers in wetherby might also come out to you?
Keith from Fox Saddlers is good, also cheaper than above - Wetherby area
Hay Farm from Huddersfield, you can take your horse there.
I've also been told that Barry Westerman (think thats his name...I do have his details at home) is a good old hand, not had him though but someone on our yard has.
