I have been running WVO for almost a year now. For me it was an easy choice. I experimented with several batches of Bio with some trouble. The way I look at it is that you need to invest some time and money upfront for WVO. The pay off is less work later on, less issues dealing with nasty chemicals, sourcing methanol and glycerin disposal.
Even WVO still has a fair amount of work associated with it. Its kind of like burning wood for home heat. You have to be willing to put the time in and not mind doing the work.
