Nice fish!! That sunset rule sounds brutal. Most my fishing for walleye is through the nite! I tagged a 26 incher this year, it went a little beter than 6 pounds, Buddy tagged a 28 incher didn't quite make 8 pounds (still waiting for copies of the pictures) I also caught and released one at 29.75inches. I'm guessing you released that eye, I don't weigh fish that are being released but there are sites around that have weight calculators, you just need a length and a girth. I think the gowalleye site has a calculator if your interested in getting a rough idea without being rough on the fish
. Nice catch, thanks for posting the pic. Tight lines.
