The answer has already been nailed. Buy your own gear if you want freedom. The property owner makes the rules.
Go enjoy crappies with your friend. Respect his preferences even if they are dumb and be content just to enjoy the day with your friend.
Once you get your own gear, then go tear up walleye, night fish burbot, set rigs for pike, and cover water as much as you want. Do whatever. Invite him to go under the pretense that you are now going to try your ideas. He may take to it, he may not.
We are all individuals with different preferences that contrast even more in fishing.
I like to fly fish and vertical jig with ultralights. When I invite people, I’ll do those things. I’m not a fan of trolling but when I go with other people, they want to troll. So I troll. The owner of the boat is the captain. Concessions can be made but I never push them.
I fish with my favorite setups and take extra steps to help odds. Then I’ll have a guy in my boat who ties a crankbait on his ultralight to troll with no leader. I dont offer advice unless asked for it. Even if I outfish the other guy, we both got to do it exactly how we wanted to. Older guys often resist trying new ways. I just let them do it how they always have. Lastly, fishing is arbitrary. My way is not the best, just different.
At the end of the day, we just like fishing. My libertarian principles kinda infiltrated my reply.
