I think Big Horn makes THE BEST cordura saddles. My very first saddle was a Big Horn cordura. I've since moved on to "better" saddles, but I still keep my Big Horn because it might be the perfect fit for a future horse. It is about 15 yrs. old and still in great shape.
The only caveat is make sure it fits your horse. I think a bad fitting corura is more likely to cause pressure points than a bad fitting leather saddle because the skirts aren't stiff enough to disperse some of the pressure. But use a good thick pad, and if the saddle fits the shape of the horse's back, it shouldn't be a problem.
I wouldn't paint the fenders. It would look even uglier than the pattern already on it. I actually kind of like the patterned cordura!
I was once told by a friend who buys and sells saddles that cordura saddles are "disposable." I had no idea why she would say that until I started seeing corduras made by other companies. Most of them are total junk!!! But the Big Horns are top-of-the-line in corduras, from the saddles I have seen in person anyway!
