The 140 BKS Blue Ocean is a "must have" tropical lure. These things are designed to catch literally everything in tropical climates, such is tunas, mahi-mahi, roosters, jacks, snappers etc etc. Built for big teethy fish the BKS series is a must have set of lures any tropical angler has to have. Ideal on rod set ups with casting weights from 40-100g, I used these on a Tenryu Diablo 20-110g weight range with PE4 and an 80lb leader, the lure swan perfectly well.
Personally I was blown away by how good these lures are when I fished in Panama in 2018, I cannot believe I haven't tried them elsewhere.....but I will.
