I tried to post this in the 'saddle fit' sticky, but the thread is old...
When I bought my horse I also bought the saddle that had been fitted on him. Since it had been fitted he had put on weight and it no longer fit him that well, but I bought it so when he lost the weight it would fit him well. I used this saddle for jumping and didn't really like it, the stirrup bars didn't have stops so the stirrup leathers kept slipping and once fell off and took me with it, which is an experience I don't want to repeat. William took a while to settle at home so he wasn't ridden very much at all, so putting on more weight made the fit feel much worse, the gullet pinched him at the side of the spine and I felt very 'perched'.
I found an ad for a £100 saddle in the paper and it just happened to be perfect sizing for me and him. I bought it just as a temp until he lost the weight, but I feel much safer in it, it suits my needs much better. Now I ride often (nearly every day) and William is now a good, normal weight therefore my beloved saddle doesn't fit him very well. I use a Polypad which is a thick saddle cloth to pad out the excess, that works. But now it is summer and I want to show, compete etc and want to use light weight numnahs. I really want this new saddle to be refitted! Is that possible? My riding instructor said she has a number for a 'saddle fitter' as her horses have changed shape a lot this year. I don't know the make of this saddle or how to get to the tree... so my question is can it be re-fitted or am I looking at investing in a new saddle? I'm at the point where I am thinking of putting him old saddle back on, but it isn't safe for me to ride in.
Sorry its a bit of a book, just wanted you to know where i'm at. Any advice?
