Can’t help with your question as I’m all Lowrance but will throw this out.
I returned about 2 weeks ago.
Niagra Reef was by far the hot spot as far as the jig bite was going. We were always able to find clean water there. everywhere from 6′ to 15′ was producing at that time.
Trolling was best for us E NE starting just outside of “C” can. We’d start there and then head for islands.
DDHJ 12’s way out produced any of the reef runners we used.
All fish caught trolling were 27″ and up.
At that time it was from 35′ to 65′ back of boards.
Don’t be afraid to maybe try some jigs with a stinger tipped with crawlers. Have fun and please report upon your return. Wish I was going back!!!
