I know it's a little late on this posting but just adding 1 1/2 cents worth. I have had two heart attacks and a stroke and now I am retired so I do fish alone a lot. Not too many of my friends at my age are retired ! But I did promise the wifey I would not only buy but wear a decent life jacket. I was at BPS and shopping for a new jacket when the sales guy showed me the new inflatables . I tried on a few and was really surprised that the one on sale for $79.00 was the comfiest. It is simply an Onyx A/M 24 with the BPS label. But as stated here. I don't wear it for the game warden, I don't wear it for a tourney, I don't even wear it cause I told the wife I would. I wear it cause I'd like to see my Grandkids and Wife, and kids, after falling out of the boat when something does go bad. As far as Auto or Manual, If I can wear a contraption that is smarter and quicker than I can be to save my life, well what the heck I think I will. That's just my 1 1/2 cents worth. To each his own , I was also invincible at one time too. Tight lines to everyone...
