FQHB and Arab bars both have a flatter surface, from what I understand, but arab bars are a bit different in that the surface changes a bit toward the back for a better fit. I'm still not totally clear on the difference.
That said, our older (25 years old) crates barrel saddle has FQHB (according to serial number) and fits our arabs well. My mom's newer Billy Cook also has FQHB, and sets the pommel right down on their withers, as it is too wide for them. We recently purchased a middle aged Circle Y in a semi-QHB and it fits both arabs very nicely.... If you have the opportunity to try different saddles on your horse (maybe saddles that your friends own, who have serial numbers and such to verify make and tree size, as well as age which can also make a difference) find the one that best fits, and then buy one with the same tree, in the same brand, and of a similar age, or at least the same measurements. Unfortunately, not all trees advertised as FQHB are the same size.
