i ride in extremely steep terrain all the time without a breastcollar and my saddle doesnt budge. it fits my mare very well and she’s got good withers.
i have a trick to remind me to tighten the girth before i get on: i wrap the latigo around the stirrup until the third cinching (i tighten the cinch in stages) . only after the third cinch do i put the latigo in the keeper.[/QUOTE]
Good withers won’t stop a saddle from sliding backwards. Girths can break (even good ones in good repair, I’ve seen it happen.)
I don’t have a latigo, though I could see doing that by not putting my stirrups down until the final tighten. Again though, there are other reasons they can come in handy.
