Re: Non-Washable hoses...
You won't have rust issues with non-washable hoses if you do it right. :P
I have yet to have any flavor ghosting issues with either of my KM Ultimates. So far, so good. Plus, I like the draw MUCH better than the Razan I have used. I almost ordered one today, but it would be waste since I already have three KM hoses that smoke better. Plus, they are pretty.
