I use power pro 10/2 on all of my walleye trolling rigs. Okuma magda 20's and 30's.

I use Precision trolling data for most of my trolling applications.

I just pulled up the Bandit 300 series (as an example). To run a 300 series at 8ft you would need 19 feet of 10/2 braid. Conversely, you would need 25 feet of 10lb mono to reach the same depth.

If you are not familiar, Precision Trolling data used to be a book that was published with all the tops baits and their specific dive curves. They have since gone digital and almost all bait are available. They have an app for Android and I-phone that you can download (free of charge). You can purchase the entire package of all lures in their catalog (with charges) for one set price (around 65 bucks) OR, you are able to pick and choose the specific lures you use and download those lures for a flat fee. I utilize many different cranks and lipped baits for trolling (walleye, crappie, etc...) so I have the entire package of lures.

It will show you an example of the bait (a picture), and have drop down charts. The line chart will have either Berkley 10# xt or Berkley 10# Fire line. We have found that 10# in either mono or braid correlates to the same as Berkley so you don't need to be concerned with buying that specific line. Most guys run the same size braid to ensure their dive chart matches. One you choose your line, you can choose the number of feet down you want to go and it will automatically tell you the number of feet back. Additionally, if you were previously running a bait at a set number of feet back, you can choose that and it will tell you exactly how deep you were running your bait.

I don't work for the company or get anything for telling anyone about it. For trolling, they are known as "The trollers bible". I do know some of the guys that actually test and develop the dive curves. Many of them are done with actual divers in the water observing the baits as they go through the column. Pretty interesting stuff in my opinion.

Hope that helps
