Looking ahead to future diving and wondering about stage tank attachment. The stock Ranger has no left waist D ring, only a lower ring. As far as my reading the traditional points are the chest or shoulder ring and the waist ring. On the Tech model there is a D ring forward of the weight pouch. Could a ring be sewn to the Ranger like it is sewn to the Tech, there seems to be the same space available? Let me know how the correct rigging is done. Thanks
