I use 1 and 1/8" ID hose that I picked up and the Borg, its very lightweight even compared to shopvac hose. A couple pipe fittings adapt it to shopvac hose and then I get enough length to toss the shopvac out the back door to cut down on noise. I posted a couple pics on the binaries group a month or so back with the hose in my PC 892 router.
