Randy, the dual bladder Delta float is the one I use for wahoo. it has a grommet for holding your dive flag, and a continuous loop of webbing from front to back for rigging multiple floats in series. You can check them out at
www.foxfloats.com. Scubadown16 is in baja right now with a couple of other spearos using these floats. The cost on the Delta float is $125 plus shipping. If you have any other questions, or would like to order, please feel free to email me.
Thanks, Justin Fox
