I have a 32 blackfin with 3208s and the range is limited-so I want to add capacity. I heard that feul bladders are a good way to go-does anyone have one? Can anyone give me makes models or a good supplier for 100-150 gal sizes. the only one I have found is Aero Tec Labs at pillowtanks.com. They sound pretty good as they are used in military applicaions but it would be nice to get some feedback from someone with experience. Thanks Chris.
