I have a 16" Circle Y, although I almost never use it. The seat fits me, but I don't like where it forces my legs. We have a 15" Abetta...a bit tight for me, but I can ride it. We have 2 DownUnder saddles, a 17" and 18". The 17" fits me OK, but I only have about 1/4" between my thigh & the poley. The 18" is a touch big, but gives me some wiggle room.
I'd add 2" to what you ride western, but it will also depend on the angle of the cantle, how vertical you like your thighs while riding, and your technique in posting.
