^^^^^^^^While all that is true.......it is also true that Teflon lined hose is heavy, not very flexible and both the hose and ends are expensive.
I haven't weighed a foot of each type hose of the same sizez with aluminum ends on them so I don't really know about the weights of each, the TFE is usually a lot smaller O.D. than the non TFE hoses of the same size and your correct on the flexability of them, not good for sharp corners so I try to use 90 degree elbows ends for those applications.
