Not really true
I'm funny about king hubs because when they skip, they spin and you're pretty much f**ked. When a freewheel/hope skips it generally just skips to the next engagement of the ratchet.
you can send your king off to tarty and they'll sort it for you, i'd ask for adam to do it though, as jamie moxon had some issues with his from them.
Echo Sl's are pretty good, there's a lot of them broken because there is a lot of them sold. They're cheap though so people don't mind shelling out £60 once a year or so when theirs go bang. however freehubs are more of a long term thing.
I ain't keen on freewheels, but there's no real reason why.
My two cents anywayzzzzzzzzzzzzz
