I would only use a hobble as an absolute last resort. Only used one once, for one of last year's first kidder, who didn't just hate being milked, she hated having an udder too, and would just kick at it too!
I know my best friend has only used a hobble once as well, and when the goat has quietened down- after a few weeks, we were both able to stop using it. Have to say, in the two instances I know of, it has been a British Toggenburg type both times!
We don't feed anything while they are being milked, I like them to chew the cud if possible. All our goats get both breakfast, and their dinner, after the milkers have been milked.
