I jump up to 1.10m in my Wintec CC but haven't in a while [we've been XC training so we're sticking around the 80cm mark for now because that's the highest the local course goes]. My position isn't perfect but I believe that's more me than saddle, I have friends who jump a LOT higher than me who recommended the saddle I bought because they liked it so much.
But, I did jump 1.05m in a cheap and nasty Kincade GP and if you know the synthetic Kincade you know they're definitely not cut for jumping. Add to that it was way too small for me [16.5 inch, I usually ride in a 17.5], and it's clear that it was a jump I made despite my equipment not because of it. I have attached a photo of Monty and I doing 95cm in said saddle... also have a photo of the 1.05 but it's like 100x100 pixels so I haven't bothered.
You CAN jump high in an AP but you will always be fighting against your equipment. If you can afford two saddles then the way to go is a dressage saddle and a CC saddle [or event saddle, same thing as a CC with a few minor differences to make it a little more secure]... that's what I've done, and it works brilliantly for me. I do trails and flat in my dressage and jump in my CC. If you can only afford one saddle and you want to jump and flat/trails then an AP is the trick. It is difficult to hold a good classical flat position in a jumping saddle and almost impossible to hold a good jumping position in a dressage.
