get a good recommended saddler out, one who stocks a good variety of saddles, and try them. it's impossible to recommend really because everyone is a different shape and has different preferences.
having said which, i tried quite a few and the Ideal saddles were the comfiest for me and fitted my mare well. made-to-measure, your choice of colour, size, type of leather etc etc, less than £1000. well worth the money, lovely saddles.
After 4 mths of trying to find the perfect saddle for my mare & I, i ended up with a berney bros international (google it) compared to my mums k2 its as amazing if not better at the price (600 made to order) Had it 2 weeks and after 6weeks of my mare being out of work & lots of bucking its kept me in!
Ohh ive just looked on the fusion saddles website and are really nice, I think ive found my next saddle!
train_robber - that is you on their website isnt it???
Thanks everyone. I will of course get a fitter out - trying to get a guy that stocks Ideal as many of you recommend that. All your advice is much appreciated.
