There is a 73 psi pressure limit imposed on hookless setups, but most users won't need that much pressure. If the zipp pressure calculator calculates a higher pressure, it will suggest a larger tire and/or a wider rim. I weigh only 60-62 kg, so that's not a problem for me. A 100kg rider only needs 56/60 with a 32mm tire, but with a 28mm tire on 23mm IW rims, it's still only 65/69.
Another big advantage with hookless is a fabulously smooth ride and no pinch flats. The down side is a lot of older frames won't take 28-32mm tires.
