I like the neoprene style full vest when on questionable ice, I don't trust the inflatables in cold weather because they need temps over 32 degrees to
activate in a timely fashion. At least according to the manufacturers, personally I have never tested it.
Plus the full vest provides some added insulation, and neoprene stays flexible in cold temps.
For boat fishing in reasonable weather I do like the freedom of the inflatables, other than my buds trying to yank the manual rip cord!
