I’ve been using flex/braided hoses for many, many years. I’ve noticed zero wear on my hood (which covers my neck seal) so no issues at all.This right here is why I am glad this question was asked. Miflex hoses are very appealing with their flexibility, light weight and pretty colors. I would really like to try them, but I can't risk them wearing into my wetsuit or especially my drysuit.
And Achim from InnerSpace Explorers uses them too, which is a pretty solid endorsement, I would say.
