My boat is stinky. My hoses fail the "Wipe Test" and I'm changing them out to keep the ladies from abandoning ship.  I've read all the posts and tech articles I could find on the subject and gotten a lot of help, but I don't see any recommendation as to the various choices in sanitation hose selections. I've just seen the suggestion that says get the white one, not the black. When I research on line I find at least three choices. 1. MPI, white reinforced at about $3.37/ft, 2. Raritan sanitation hose which claims 20 times normal odor protection at $ 8/ft. And 3. Sealand, super flexible claiming superior odor protection $14/ft. (all these prices are for 1 1/2 ")
The last two provide a 5 year odor proof warranty.  I'm a real cheapscape, but don't want to be penny wise, lb foolish and I don't want to do this job again in five years. has anyone had any experience with these?? I'll appreciate any comments.
