I‘d drop your water bowl size for a sling. As the guys have said the size of the sling is the most important part. I try to use tattoo ink cups for my slings or very shallow bottle tops, for one of my smallest i cut off the bottom of a covid testing tube. So they’re’s no risk of drowning. With slings it can be hard to tell if they’re feeding so a bit more space for food might be good.
