In recent years I have enjoyed roughly 20 days each year with guides in their drift boats fishing rivers in Washington or nearby states and providences. The economy and its impact on me has me thinking about replacing many of my guide trips by using my own pontoon boat supported by fly shop shuttles. I expect I will often fishing alone. So I am now considering what I should use for a PFD especially when I am fishing alone. I want a first class, comfortable, reliable PFD that doesn't interfere with my physical movements while I fish or row. I think I want to avoid bulk so I am leaning toward inflatable. One choice is the Sospenders type. As you probably know, they come in two styles, one inflates when it gets wet and the other requires a manual jerk. Another choice is inflatable fishing vests made by either Mustang or Stearns. The fishing vests require the manual jerk. Is there a quality third choice, inflatable or not, that isn't too bulky? The fishing vests are hard to find, probably because they cost more than the Sospenders type. So I have been unable to try them on first hand. Cabela carries the Stearns in their catalogue. If I go with an inflatable, do I want an auto inflate or manual inflate type? It seems to me that the vests seem far more useful than the Sospenders type. I solicit your collective experience and wisdom. Thanks.
