I'll go with 3.
I wade with one rod and a small sling pack that carries a single 3500 box, a couple or few bags of plastics, pliers, line snips, and a can of snuff. I do use a rod/reel combo and boots that are pretty far advanced compared to what I started out with 40 years ago.
I have a modern sit on top kayak specifically designed for fishing that I'd call advanced technology, but I keep that simple, too, with no motor or sonar, which aren't needed because I use it to float fish easily readable smaller rivers from put in point A to takeout point B.
Same deal with my 13' whitewater raft, which I use when I have a partner or two. Its fabric and construction are technologically advanced compared to inflatables from the old days, but I made a row frame out of treated lumber that could accurately be called rudimentary. And my anchor system is lengths of logging chain tied to a rope that I drop off the back of the boat then half-hitch to a d-ring. I don't use a trailer, either. Instead I inflate and deflate the raft each trip.
Generally I like to keep things simple with my fishing and other parts of my life. Money does play a role, too. If I had a lot of it to spend, I'd probably buy me a rigged out river jet boat.
