I have a V6 speedbag, and will be getting a V12 in short order. I also have an 1106 worm bag, with another one on the way. As to capacity questions, I have found that I can get more tackle into six Falcon boxes (specifically: 302, 303, 501, 703, 707, and 708) than I could previously fit into four larger 3700-series boxes plus the clunky, square spinnerbait box. The worm bags are also great, much easier to use than a binder. But I have to say, after reading about the cooler idea, a little insulation would be a welcome addition to protect the plastics from these Texas summers.
