Our sponsor shop Rod Builder's Workshop carries them and Smitty swears by them. He's pretty particular about the gear he uses but he uses these all over the country when he's hunting or fishing.
I have been looking for something very light to use for fishing certain flats where wading is risky due to extreme tides. Something like the 15 pound unit they talk about would be too easy to carry to resist trying. The problem is when the tide goes out you have to walk 3/4 mile to water sometimes. When it comes rushing in it brings hordes of hungry fish, but you have to then get back to shore somehow. Something that is very light and packable for a little ways would be key to this fishery.
It's the one they haven't put pics up for yet... the "bruin" I think? Curious to see what it looks like.
