Actually, I’d skip Leech too. A good guide might get you on some crappies but I’m not even sure about that. They know the crappies are nice but not “a lot” of them. Not sure they would guide you to them?
From my own experience, the perch quality has gone down in the last couple years too. Lots of dinks with a few nice ones mixed in.
So, unless you’re set on a Minny trip, there are better places for perch and crappies…but both…I’d like to find that place too !
Good luck!
