big bait = big fish.....i have always gotten the bigger fish when i head off shore for them...but i have always caught the bigger guys in the mix with the smaller ones...i think its hard to target just big ones as blues are school fish and the big guys are with the small guys....but the biggets bluefish i have ever gotten was a 17 lb brtue that was caught off the keyport #1 can about 6 years ago...we were just fluking and i decided to throw a bunker chunk out to see what would happen and we got him, amazing fight.....sorry to go off on a tangent, but i have always had good luck with the bigger blues at the 17 fathoms, ba bouy, farms, and drifting over random structure
