I've been using Knightsbridge for a while now and wanted a change. As I like a tobacco flavoured vape, I liked the sound of Route 66. I first tried it by itself and found it pleasant enough but quite 'dry' and an after taste of vanilla. I mixed half and half, Knighsbridge and Route 66 and it worked perfectly! (for me anyway!) mellow flavour and a good all day vape.
