Forward Flap English Saddle?

  I am six feet tall and have a very long leg from hip to thigh. I am having trouble finding a saddle that is big enough. My knee always over shoots the flap. Does anyone know of any saddles that are extra forward. I ride in the jumpers, and I fit a 18 "seat size.
Some of the saddles marketed as" cross country "saddles have very forward flaps. Maybe you should try one of those out.
I am not as tall as you at 5 '10 "but I have an 18inch GP saddle which I had made. I ride with quite a long leg as I do distance riding but didn't want to go for the usual treeless Torsion saddles that most endurance riders seem to favour . A brilliant saddler was recommended to me who looked at me and my horse to see what would suit us best, quote "big horse and big girl to ride her". Suprisingly the saddle cost nowhere near the commercial lines such as Bates etc. It is very simple, no gadgets, removable blocks or anything silly but a leather handcrafted English saddle, beautifully made using buffalo leather (which is thick but very flexible) and bespoke! The total cost was £ 850. It is worth trying to source a decent saddler as you will get exactly what you want and something that fits your horse AND you. Good luck.
