I can tell you from actual experience from multiple years and various diving conditions....the Zeagle Tech is designed with the serious sport diver in-mind. The wing is a large lift 65lbs. wing that can come off and be replaced with a smaller wing if one desires. I persl. dive its streamlined cousin the Zeagle Tech Pac which is a well designed technical diving platform. I use this for both steel doubles and steel single configurations. I have on occasion used it for diving a single Al80 and it does the job, but its focus is really on doubles or larger steel singles. The wing has a uniquely designed and well fabricated wing strap system....this allows the diver to adjust the amount of wing 'tacoing' that will occur on any given single cylinder. I persl. use a full Zeagle backplate in place of the 2 smaller doubles mounting plates....provides a better ride and the added wt. you many times require on trimming out your rig. Both units are HD in construction for many years of great service. You can dive doubles with the Zeagle Ranger and would aford a suitable platform for someone not diving doubles all the time and using them in more the recreational sense. PM me if you need any more specifics.
