For literally months now, the ONLY 40+ leve for leathercrafting I'm offered in Gridania (yes, home guild city) is Hungry Like the Wolves. This local typically offers 5 attempts and requires running to Nine Ivies to complete the leve, which is almost not worth the effort of teleporting to Gridania, and then running all the way up there.
Other crafts, weaver, most particularly, offer a wide variety of 40+ local leves, not only in Ul Dah, but all cities. More often than not, leathercraft offers ZERO 40+ leves in Limsa, and generally only one in Ul Dah.
When you get around to 'balancing' local leves, kindly consider this.
