I talked to one fishery here and they said the DNR wouldn't let them sell RES north of I-94 (runs from Detroit to Chicago). I live only 4 miles north of that, so RES probably will do "okay". the last two winters here were a lot worse than the previous 7 that I have lived here. this year, we had ice from Thanksgiving until the beginning of March with no thaw. I think I will go with PS, but take a year to see if I can find someone who sells them. If not, I will start my slow stocking program next spring. Thanks for the input. If I went RES, should I also wait until next spring?
