It always helps if you can match all your gear. As in the same reels, line, planer boards, etc. This will help keep your spread even and also help you duplicate depths easier when you start dialing in your program for the day.
The only exception is we use different length rods, running the longer rods on the outside.

When you first start it is easier to run only a couple lines on each side until you get the feel.
And don't let a tangle now and then get you down, it happens to everyone. It gets better with practice.

Last check your lines often. Walleye are notorious for hanging on, not to mention little whites etc,

Good luck, have fun, and I hope to see you out there.
