So I've decided it's time to graduate from my 357's which I love, to a rebuildable. Once I got spoiled on the flavor of dripping I could never go back to my cartos or carto tanks. I just ordered my first rebuildable, the Cobra and I want to be well educated by the time it gets here. I'm expecting issues, being that I'm a rookie and would love someone to point me to the best tutorials, either video or written. Thanks!
