Here's a guy who upgraded his Everlast OEM 26 Euro torch to a CK Worldwide 26 Flex torch with an UltraFlex cable, and a Clamshell Dinse connector, which is undoubtedly a little more costly than the new Everlast line of super flex hoses and comparable RotoHead torch stuff which approximates the CK stuff, especially because the Everlast assemblies integrate the Dinse/gas connector into the hose, so it's not a separate item like the CK clamshell connector is. But, again, the separated Dinse connector could be a benefit to some.
