Does anyone remember what kind of a campain happened in the 70's to kill double hose sales? What kind of a hate smear took place for the anti double hose mentality to still be going strong fourty years later. Did the breathing of single hoses progress so far past a factory DAAM that no one wanted to buy one? The only stock double I have is my Voit 50, and I happily dive it over my rebuilt 109.
