Some reasons I am heavily considering them:
*Light weight (compaired to most leather western saddles)
*security for riding
*Supposed to be easy on the butt & back on long rides (horses back too)
*Riggings for saddle bags (unlike my English saddle)
The western saddle I have is a Big Horn cordura, and it weighs about 17lbs. Which I love. I can grab it by the horn and flop it up onto my 15hh gelding. Right now my sister in law is using it on her 14hh mare because she only has an english saddle and perfers a western.
The western saddle I am using (which belongs to my father in law, who doesn't ride) is super comfy, but is easily 35lbs, and surely not my favorite to get on my 14.2hh mare, let alone my 15hh gelding. Lol. Plus it's a smidge long for him (in my opinion) and I don't want the unnessary weight on the trails. Especially when we ride in the mountains & have switch backs & such.
This is one of the saddles I was looking at
