Re: looking at KMs
first of all the second one is sold out so unless your up for a wait your going to be getting the Sallah.
1. No, the hoses that come with KM's are leather and have the metal spiral inside so they are not washable.
2. With KM hoses they do stick out a bit and aren't exactly prone to just tipping because of this they need an outside force to knock them over, if they are pushed in correctly that is, but the hose that comes with the first one you shouldn't have an issue.
But, I would still recommend some sort of washable hose like the Nammor.
