There seems to be more methods to brew a pour-over than any other method. This may be because there are so many different shapes and materials of brew cones and paper and metal filters. Every little detail will result in a different method and final brew quality outcome. Some things remain consistent regardless of which cone and filter combo you use. Pre-heating the cone and rinsing the filter are mandatory. The style in which you pour the water over the grounds is crucial. You want to acheive a uniformity of extraction from each coffee particle and the size, shape, and material of cone and filter will require a specific jive from you in order to get a decent cup.  Experiment and good luck!
