I like the Pampa :). It's light, about 12 lbs, rigged with English girth and 2 inch Blevins leathers. Fiberglass tree. I tried it last Friday and am going to do another 10 miler Wednesday and Friday.
It was weird for the first few miles with the more English type leathers (position and lack of fenders) I kept bumping her sides...but after I worked on getting my seat right I got the hang of it and wasn't bumping her anymore.
I wasn't sore after 10 miles of trotting and gaiting and I was actually having fun posting while my TWH was getting an F for gaiting and trotting instead. The seat was comfy, as was my leg position.
The only thing I didn't like was the English rigging as the saddle slipped back which happened the last time I tried English rigging with this horse. So it may be me not tightening it enough or my mares back.
It does attach pretty far back. It's supposed to...but it moved back significantly on the ride. I'm going to try a breastcollar tomorrow and if I keep it, maybe a mohair endurance cinch? Anyone tried that? Thoughts?
