I like my vest for no other reason than that I can't stand modern **** which mostly is about style vs. function
. And I'm 31 -- can't even think about how grouchy I'll be when I'm in my 50s-60s.
Vest works great -- I prefer it for holding my net and clippers at easy reach.
The only way I'd use a different system is if I needed to fish really large flies and they wouldn't reasonably fit in the vest. Larger fly boxes are difficult to carry in a vest IME. For bluegill and trout and light bass fishing the vest is great.
