About 22 lbs with endurance stirrups (which I need to get back as some point
). Over 24 lbs with those brass monsters that came with it. I could put on nylon stirrup straps and drop another lb if I wanted.
My issues with the stock saddle (traditional Australian style):
1. I'm not a fan of the non Western cinches, but I have broken down and bought the addapters yet.
2. I perfer a rear cinch ring, because I perfer to rig my cinch from front and rear (they have lot's of different names for it today that we didn't have 40 years ago
3. They don't give as much surface contact as my Troopers.
4. The outside and underside flaps are way larger then they need to be, so that's a lot of extra weight I could do without. I mine was a a Syd Hill and I might want to sell it one day I'd cut about 18" off from the bottom. I could make it way about 18 lbs with some judicious alterations
That being said, they are great to use when training a horse. I find them to be very comfortable. Pretty easy to make changes to (e.g. stirrup straps, cut away excess flap) I'm a fan of surcingles (most distance riders or working riders should be), and stock saddle are amoung the few designed for their use.
I've yet to find the perfect saddle for everything I want but I'm ok with having different ones to meet my different needs. The tough part is keeping horses that are about the same size so I can use the same saddles.
