Ok, so I had my old tried and true Precision Trolling Guide. It was the old cardboard type pages, and it had mini disks, and a bunch of stuff that aren't in the newer ones. Left it on a buddy's boat, and it got lost, so he have me a new Pro Edition. Nice upgrade, you would think. I can deal with the fact it doesn't have some of the things I used a lot from the old book, like the disks. What I don't understand is that it says New Plastic Pages, but the only pages that are plastic are the cover and back. All the pages in the middle are cheap thin paper. Not going to last 10 minutes on a wet day. Definitely not better than the previous cardboard stock type.
