Saltwater gear to freshwater.

Why do people laugh at me when I use my 10' surf rod for bluegills?

jk. So i grew up fishing saltwater but moved inland (Adirondacks NY) some years back. The lake by me has some large pike, walleye, trout and such. I've been catching fish with my lighter tackle, but recently got a boat again and wondering if any of my larger saltwater gear can be used and what i should start selling.

Obviously my 6/0 reels are out, but should I even keep a 4/0? And will large pike or walleye strike larger lures, I have so many bunker spoons, Mann's stretch plugs, tubes and umbrella rigs. Pretty much standard striper, blue, weakfish gear.
