Tune or other lightweight cable housing

[tommasini]

Any updated suggestions for locating lightweight cable housing (lighter than Nokon and similar). I've learned to check German ebay but the few times I've seen Tune housing there the seller won't sell to the USA. Several posters suggested (here or elsewhere) that recent Shimano or other hydraulic hose might work.....and that they were going to give it a try......any update on any successes or other suggestions?

thanks in advance!
