For YFT and most poundage, CDB is correct. However, for BFT, I prefer jigging with a heavy Williamson speed jig, a uv flashlight, at 50' to 150', find the sweet spot depth... Maybe have to change out the lure color/size. So maybe CDB is correct all around 'cause my technique is not really one choice and chance. Regardless, I've caught 25+ BFT on one trip (and occasional YFT on most trips) using the above technique, and let others reel lots in, and give most away. But that's geriatric thrills. (Usually go out 10 times a year, haven't been out for a year, just got 2nd vax, currently signed up for 8 trips... we old guys are more horny for tuna than...)
