I think what Toby and a few others are interested in is reaching some rocks or points a little farther out than whats possible wearing waders and retain the safety of a wetsuit. I think the inherent danger of having your waders fill up with water is as deadly as any other fishing accident.
I doubt that their looking to fl;oat around with the currents catching fish like some maritime johnny appleseed
IMO, its more dangerous to wade out to a far rock in waders than a wetsuit.
