Mum might just go bareback, she has the balance for it and we wouldn't have to worry about saddles for him.
Take one look at her and you'd think she was really into the Parelli but the reality is that Man has huge emotional issues and the only thing you can ride him in is the halter or he rears (bit, mechanical hackamore, you name it we've tried it and it's the rope halter that works for him). We knew he was going to be a tricky horse to figure out, we just didn't know HOW tricky!
We've always got a saddle saga going on here, it seems. It took me a year to find the right saddle for my old horse, which thank goodness also fits Monty, although it is a dressage saddle and I'd rather spend my time jumping so sooner or later I'll be in the market for a jumping saddle. And there's the ongoing saga of Man's changing shape, of course. He arrived underweight from the stress of travel (only 3 hours but he looked like he'd been shipped the length of the country), and his shape has been in constant change ever since, while he builds the proper muscles up again. He was in a very incorrect way of going for a very long time. It's only within the last 3 months that Mum's even been able to get a trot out of him, he used to amble or pace, and he's a QH, not a gaited horse.
It's a saga for sure. Turns out the treeless isn't right for Man but hey, there's no one saddle that's the solution for every horse. Probably the saddle he's been happiest in was the wintec western, but that's too narrow now. Off to try to find one wide enough!
