I've often seen advice on here that you need to start with a narrow tube (proper size, of course) and work your way up to larger tubes. This is supposed to promote even development, as well as help keep the scrotum from getting pulled into the tube. Since two-stage tubes are a much larger diameter than single-stage, is there a problem with uneven development when using a two-stage tube?
