Bill:
It would seem to me that you should pick the guides brain hard… After all you may using his techniques following your successful outing. I have been there in late July and it is pretty much the same fishing for walleyes every where you go… if you are fishing deep, you want weight for jigs and lindy rigging up to 1/2 oz. for sure, then maybe a bit of stuff a bit heavier, bottom bouncers we carry up to 2-3 oz. and then I have 1 oz. rubber core sinkers for other applications that I can slide on to add weight if needed.
For the most part you ‘ll be looking at reefs and tips of points that are in water deeper than 40′ of water topping out in the 20′-30’ range in most cases, but again your guide hoipefully has more timely info for this year.
