Sorry, I forgot to answer the question about the braided hose on the inlet. You can get screw to barb connectors, but I wasn't sure if a plastic connector there would get hot or not, so I just bought two of those. Makes it easier to unplug as well if necessary because of the JG speedfit. Originally it came with hoselock connectors, no way I was ever going to put them on. I've vowed to rid my system of hoseloc. Except for the hosereel it turned out all right.
Pretty sure the microbore from Gardiners comes from Streamline as well. So far so good, the first 100m was a duff batch I think, this one is holding up well. Funny how much difference one setting on the varistream makes. At 6 it doesn't swell up that much, at 7 it's much worse.
