If you are mainly focusing on dressage with the occasional small jump you could even get away with a dressage saddle now. Jumping in a dressage saddle at low heights is fine, because your hip angle is rather open at lower heights you can keep your seat quiet well in the dressage saddle. I have even seen people ride full courses at about 60cm in a dressage saddle at riding club.
I used to ride in a all-purpose for pony club. I like how the cut of it I could have long stirrups and short stirrups and it felt fine either way.I could practice dressage with a nice long leg and I could jump quite comfortably up to a metre. I alsoused my AP for gaming when long stirrups are needed for mounting easily on the run and stretching down low etc, I find it a great comfortable and versatile saddle. I still use my AP for trail riding with the occasional log jumping in there. (I have a Wintec 2000 AP that is about 12 years old)
As for a close contact, great for jumping and flatting with short stirrups but I find trying to ride with a long stirrup and leg in the CC is not very comfortable. The flat seat and the cut of the flap are made for short stirrups so you won't be able to get the leg contact you need for dressage. So if you are training mainly for dressage you won't get the most benefit from this saddle.
Hope that helped somewhat, I tend to waffle on a bi sometimes...
