What!!!
IMHO, anyone who considers no difference in the taste and texture of a 2 -3 year old winter chinook with a mature summer summer chinook, simply ain't done much winter chinook fishin'!
Maybe part of the reason is we don't tend to freeze the winters (perhaps because their typically diminuitive size lends well to that nights dinner...)but in my humble experience, 100% of the folks who have sampled fresh winter chinook have considered it to be the best salmon they've eaten. I believe its more a texture thing than simply the flavor, but no doubt in my mind - they're simply better!
They're not always smaller either - back in the late 80's at Kingcome Inlet I guided to a 42 lb bullet in early May that had milt sacks smaller than a pencil. Looked like a HUGE shaker!
