What saddle; brand and model is best for this CC fit

What saddle has a semi-deep seat, narrower twist, wool flocking,
AND also fits a WB with medium wither, good shoulder and a flatter back.
I can find fit for rider or horse build, but not both. Flat seat seems to equal flatter back fit and vice versa.

What brand and which model of said brand? Thanks so much for any input.

I’m now riding in a Frank Baines Elan CC saddle that sounds like it might work well for you. I ride a TB with wider withers (a unicorn) and a larger shoulder and it works well for her, AND me. Narrower twist. They’re easily adjusted as well. Haven’t ridden in something that has such a nice mix of comfort without feeling like a poofy Laz-E-Boy underneath me in a long time.

Let me know when you find it. Black Country Solare might do it but definitely not a narrow twist and I couldn’t love it though horsey seemed to. I ended with a Tad Coffin Smart Tree. Checked all my boxes (matched yours) but no wool flocking. It was a bear to get used to after my couch of an Antares but I love it now. Flatter backed horse couldn’t do French trees, generally.

I had a giant tb with a similar build and had a Frank Baines Enigma for him - it was for jumpers and fox hunting and had external blocks, so I wouldn’t use it in the hunters/eq, but I believe that tree shape would work in a different model if you need something more classic. My saddle fitter told me that brands from England tend to be better for flat backs. I loved that saddle, narrow twist, deep seat, very well made, and broke in quickly despite sturdy leather. Of course it doesn’t fit my current curvy backed tb who insists on French trees only.

Look at Hastilow, I have the Concept jump saddle and it checks all your boxes.
