Look forward to hearing your stories on here.
As said before braid line is a must for dipsies or Lite Bite divers. Mono is best for running stick baits. Harnesses can be used on either set up. You might want a couple size 40 jet divers also and a couple 30 jets if you don't have the boards. You can flatline them off the back and have success up high. Trolling during May through October is 2-3mph. If you are in colder water times, you might need to get down to 1.2 mph or so for speed. If you boat can slow down below 2mph, you won't likely need bags for a while.

I have been using Okuma counter reels in size 27 for 15 seasons and only require adding lube grease every year so far. The counters still work with a little jimmying. I replaced the mono a couple years ago but the braid is still good according to Craig at Erie Outfitters.

Not sure where you live but Craig is in Sheffield Lake and a great reference.
