I think my Abetta is very comfy - I think different body types, etc. have something to do with that. I loved my Aussie saddle - but my husband hated it.
My horse seems to like the Abetta much better than the Aussie. It fits her pretty well overall. Of course, rider weight impacts that too. She didn't do too well when I rode her in the Aussie, but I wasn't sure if it was the saddle. When her trainer rode her in it (he weighs about 75 pounds more than I do), she went nuts. It made the poor fit really obvious.
I was normal...then I got a horse.
