Definitely size 2 hooks but can use 4 but recommend 2. 80 lb line. 20 mm pop up tiger nuts. The big sweet corn or double sweet corn and any of the bigger boilies. Should get one in no time.
Thanks, i actually got one right after i posted this on a double sweet corn (small) on a size 2 krank hook. Got a 522lb arapaima aswell (different bait). I didnt realize how big the mouth on the siamese was and was using smaller hooks like a size 12, only catching common carp. Will try some boilies tonight. Thanks.
