I love mine. Have had it for 12yrs. It still looks good, it's probably a good few years old now. Is very lightweight and my pony has never had any back trouble.... so I'd highly recommend!
I have quite an old one. It is very comfortable and has worn very well, certainly looks newer than it is! It's a GP with a flat seat and very slightly forward cut. Has always fitted my horse (WB) well and currently have it on a TB until his saddle comes, and fits him well too. Would definately recommend.
