My actual serious answer is I think certain species are much more susceptible to dying from a gill plate hold. Salmon and trout are a prime example. You gill hold those things and they flop a bit, they are toast. Never have seen a study on walleye, pike, etc. It’s probably better to not hang...
I was discussing this with a friend and one of the things mentioned that makes a lot of sense was: If a guy nets a state record walleye, a typical first reaction would be celebration and maybe some Top Gun high fives. After that you would remove the hook and weigh. I know my first reaction...
Carp, sturgeon, suckers, catfish, walleye, etc. I have landed them all snagged in the back and tail with a jig. Not even a question it can be done on a 16+lb eye. Not saying it was, though.
Get some extra when you make your trip for Opti oil. I wouldn’t gamble on a $20k motor. Like said above DFI oil is DIFFERENT from regular 2-stroke oil.

Also, each manufacturer varies in the way DFI is done so DFI oil can be engine specific.
