I used to run leadcore on planer boards all the time. It is hard on the leadcore though. It breaks the leads thus creating weak spots in the line. I haven’t used boards with leadcore since I purchaced 2 Bass Pro Shops Walleye Angler Signature Series 12 ft trolling rods and 2 Perigrin 5 ft trolling rods. This set up gives me a perfect spread of my baits and minimizes tangles. You can order the 12 ft’ers from Bass Pro and Dean at Evert’s has the 5 ft shortie rods. I know several guys running this same set up and they too absolutely love it.
That’s the set up I run too. The rail allows you to turn the base towards or away from the water for that precise angle. You can also easily loosen a screw, and slide the base up and down the rail.
