if you go with the ISO anvil jigs, you need front and back. With post mount, you just need one. Seems like a no-brainer since you can use an adapter to get any size ISO with the post mount.
ISO is as dead as a doornail in the industry. They are shipping brakes with ISO adapters, but that surely will come to an end fairly soon. There is a fairly limited number of post mount for framebuilders though, that is one disconnect.
