Just read a good article on Jumbos (F+W Outdoors), and an interesting fact was that they mentioned crayfish as one of the best primary food sources for producing big perch. I only mention it because the last time I located nice perch on Tusc. (and holeinhide was there as I recall) they were loaded up with crayfish. They weren't monsters, but 10-11.5 inches works for me every time. Also as stated previously, I drilled a bunch of holes before I found them. Might have to revisit that spot, as it was several years back.
