Always nice to see new tubing products, would love to see some results of long-term exposure to the various coolants available though.
Perhaps some month-or-three long tests with active moving coolant to see how it reacts.
i.e. water (to test this theory of smooth wall)
water + biocide (obv)
glycol
pastel in all it's colours (because lets face it, it eats just about everything)
aurora (not that this is a permanent solution anyway)
Then all of those + coloured variations to see how resistant it is to staining etc
And again + dyes
Also how it reacts to heat + the above, so make sure loop is kept at various temperatures to see how it reacts + breaks down etc with various coolants.
Be good to know if it's food-grade or not as well.
Not an exhaustive list of tests, but I'd like to see a few before I trust a new loop to it

Due diligence and all that.
