Over the weekend I finished assembling my first set of doubles (AL80 with Highland Band and a SeaElite Manifold). Everything went very smoothly. The only thing that is bothersome is that it seems like the bolts supplied with the bands are 1/2 inch too long. Once I have the BP and wings on the threads stick out about 1/4 inch past the wing nut just far enough that I can feel it poking into my back. I did some searching and found that some folks solve this by adding a stop nut so that the backplate does not flex so far back. I am currently trying this but it would seem that you really the BP to sandwich the wing aganst the tanks. Any thoughts suggstions? The other item is that I have been looking at different tanks and configurations and the required lift that I will require from a wing. Currently, I have a 55lb wing which from my calculations the most I would need is around 38lbs of lift. So based this I could get away with a 40lb bladder. But given mfg ratings are done a bit different and that if I did really need want the full lift capabilities would it be a bit better to size up a little bit to something in the 45 lb range rather than push it so close?
