There is a lot of difference between the brands of trooper saddles. They aren't for everyone of course. More importantly make sure you get a saddle that fits your horse.
But there is a significant difference between, a Haggis, a Tucker, and a Tarpin Hill (Heskett), and frankly other really great brands like Christie, and M&W. I love my Heskett, wife loves her Haggis... Neither of us much likes the other. More importantly the saddles are fit to the horses, and really should not be interchanged.
I also see a decent amount of Endurance saddles on the trial circuit. Just saying if you are truly honest, you ought to find what you like best, and what works for the horse (Opinions are just that). Don't be afraid to ask a friend if you can try out their saddle (obviously on their horse). Ideally you could then try fit on your own horse. Keeping in mind getting fit perfect might require some adjustment to the saddle, or buying a different size of the same line. You'd be surprised how much saddle fit effects a horses gait, but if you think about it... kind of makes sense.
