Anyone Have Hose Sleeves on their Blazer?

Just wondering if anyone has sleeves (covers) on their hoses.. Trying to find out if i want to put the Stainless Steel or go the cheap way and go with nylon weave.. And are they easy to install? Worth the trouble putting. And how much do they help or are the mostly again just looks? maybe a dumb question.

I have the steel on my vacuums lines only for now. Made them out of the lines under most bathroom sinks and made some aluminum ends for them. They are just for looks and are a little tough to keep clean but they do catch the eye of others.
