OK, the pontoon is in the house (albeit still in the garage in its box), so I'm going to need a PFD. What do y'all use in such craft, float tubes, etc? I'll want something with ease of motion obviously, and maybe something that will allow a vest to be worn in conjunction? There seems to be a plethora of "fly fishing specific" models out there, and most seem a bit pricy. Is there any advantage to those, or is a regular old Wally World cheapie good enough? Thanks...
