Love mine. OK, so I'd rather have a made to measure leather saddle, but life's not like that, and I only ever have scrawny young horses who change shape constantly.
I barely clean it all year, wash it with hot water and fairy liquid in November, rinse with buckets of water in the garden, dry by the radiator, and store ready for new young horse in spring.
I've done Prenovice XC clinics in it, but if I was jumping seriously I'd get a proper jumping saddle.
It's a nice saddle. I found it difficult to jump over about 3' in it, as my legs are quite long and it encouraged me to push my feet right back and hinge over my knees. This was riding a friend's horse, owner gets on well with it.
