Life long fisherman here. I'd have to say my favorite type is fly-fishing for rainbow trout while in a belly boat. We have lots of lakes in BC that allow for trophy rainbows with very little fishing pressure.
I've done a bit of bass fishing up here and down in Florida but the fish seemed kinda small. I would imagine a huge bass would be fun to catch.
Salt water fishing for salmon, halibut and ling cod is fun, but I'll take a nice 4LB rainbow while casting a dry fly anyday.
Here's a spring salmon I caught in a stream from last summer.
A Fraser river sockeye.
