The neo-hominid morphs all have a speed of 4/12 because of prehensile feet. I guess this makes some sense if running on just their legs, but chimpanzees and gorillas (at least, not sure about bonobos and orangutans) IRL can easily outrun humans over short distances by using all four limbs for movement. Should neo-hominid morphs be able to ape* this capability, perhaps doubling their Full Move speed (to 24) so long as their hands are empty and being used to assist with movement? This increase would also apply to Rushing, as described on page 230.
* Yeah, I had to use this pun.
