I checked Cabelas in Dundee, MI and also Bass Pro in Toledo and Bass pro had one 4" Dipsey diver. Yes, only one.
All of the online places I checked were out of stock on the 4" Dipsey. So I bought two more of the deeper divers that I purchased before off Ebay, so now I have a set of 4, and 4 decent rods with braid. Which works with the 4 rod holders on my boat. I have the depth curves, so hopefully they work well. I think I am limited to 3 lines anyway if I am fishing by myself in Ohio, right?

I counted the number of lines that Juls had running mentioned at the top of this thread and I believe she mentioned 9 lines being set. I've trolled a lot in my past, over the years, but if we had two lines per person on the boat, that was a lot. I can't imagine dragging 9 lines. That would take some skills that I haven't acquired yet! So Planer boards are not in my plans yet. But obviously the more lines you have set, the greater your chances of catching fish.

Bass Pro shows stock on the snubbers so I will pick some up when I drive by there.
Is there a reason to get the 8" vs the 12" snubbers?

Thanks, Dave
