Some good news at least. I went back to the tack shop last Thursday to pick up a saddle to try on Isis. It’s a wide-tree all purpose Spanish-made Zaldi saddle. Lovingly taken care of by the previous owner. It’s very soft.
Unlike the other four saddles I’ve tried on Isis, this one settled perfectly on her back. The seat was level. Her whithers were the proper distance from the pommel, instead of sitting six-fingers up.
I’ll call the tack shop Monday and tell them I’m keeping the saddle.
Wouldn’t it be ironic if I can’t use it on her? Not going there.
