The Flex Walk perches are just one of many different types of perches I use. They've been a fun addition to rotate in and out of the cage. I don't think it's possible for a rope perch of any kind, that I know of, including the Flex Walk, to keep beaks and claws groomed - there's just no abrasive to make that happen. The thing I do get concerned about with cotton and sisal type rope perches is my bird's claws getting caught in the rope fibers - that's not even possible with the Flex Walk perches - that, I like a lot! Having used rope perches and having cleaned them, it's a pain compared to the Flex Walk perch. With the Flex Walk, you can wipe it down and keep it clean and it's quick and EASY! With all this said, I would never use just one single size perch (or type) in my cages. My goal is to use a variety of perches that give my birds the opportunity to use their feet's full range of motion. Skinny ones, where the talons almost double wrap the perch (and teach balance) to flat rock type platform perches for flat footed walking. Ok, that's a little more than my 2 cents.
