I’ve long been a fan of County saddles (which work well for me, but don’t work for everybody), but very recently (like in the last week) also became a fan of CWD… and I promise you, I did NOT want to like CWD. I’m in a similar situation right now and have narrowed it down to those two brands. I think these two brands can do a reasonable job of fitting a bit wider variety of shapes (though not the extremes at either end with the same saddle).
I also like Tad Coffin and Butet isn’t bad, but I don’t think these two brands really do the best job fitting a variety of horses somewhat reasonably well with the same saddle. I think each of them fits a very specific type better - which is fine if all the horses you ride are very similar types.
My budget pick is the Collegiate Convertible Diploma. This is another one that I think reasonably well works for a variety of horses.
Of, course, none of these will be perfect for every horse, but I think you could get in the range of acceptable.
Depending on the types of horses you ride and how similar they are, I would look for a MW or even a W (a regular wide, not stupid-wide) in a not-too-flat, not-too curvy shape. If you can swing it, maybe even get two saddles - one M, one W.
I would also definitely invest in a good half pad, preferably one that can be shimmed. My favorite is the ThinLine sheepskin pad, but Ogilvy is really popular right now; I’ve not used an Ogilvy, so I can’t say how well it would truly work in this situation.
