I'm new to the game so my experience is limited. That being said, I enjoyed trolling up the YFTs this year. We went 3 for 4 on the yft in the 40-50lb range. I love trolling and the challenge of putting out a spread to raise the tunas is getting more and more exciting. Previously my experience with the yft was chunking them up. There's just something about trolling that I'm learning to love. My second choice would be live baiting goggle-eyes to sailfish down in Bimini with Deep C. That is something everyone needs to check out.
I would have to say my favorite fish to catch, is Anything in the tuna family but mainly catch more YF then anything. We usally catch them from trolling a mix of sea witches with ballys and squid chains and spreader bars. Can't wait for summer already.
