Catching GreenLand Sharks

Well I will start this up by telling you little bit about myself and how I got in to fishing.
Im born and raised in northern Sweden where my dad fishing"maniac" had a small tackle shop that he inherited from his father.
From the moment I was born I have been my the rivers and lakes in a harness on my fathers back.Fishign runs in the family as you can see ,It was only natural for it to rub of on me. As I turned 3 I got my first fishing rod and I was hooked.
From that point on I strive to excel in my fishing going after bigger, stronger, faster and harder to catch pray.
From common Swedish bass to salmon and pike, a few years back my dad moved to Norway and it opened up a whole new world of fishing for me. Until then the largest fish I had ever caught was a 30 pound salmon.
2 years ago when I was visiting my dad in Norway we read an article on the new world record (The actual treacle http://fiskejournalen.se/jattehaj-spofangad-i-norge/ it's in Swedish but there's a pretty nice picture )Greenland shark caught just half a hour drive from where he lives with an additional 15 min boat ride. So we decided to gear up with our big halibut equipment and do some research.
After having a tackle shop for two generations your kind of bound to have some contacts in the fishing world and my dad actually now the Norwegian guide that helped the Danish guy's catch the world record green land shark. After a few phone calls and conversation we got the actual cogitates for where the giant was caught.

The Rig was fairly simple we had a 80-130 lb boat rod and a Penn international 2 speed reel with about 2000 yards of braided line with a top shot of 500 pound mono with 2 hooks rigged to a 12 pound Atlantic Cod.
We had to anchor up at an area with a depth of around 400-600 yards deep and chummed at 300 yards depth to GE them up from the depths.
We chummed all day from 7 in the morning until late afternoon without any bite on the big rig .
During that time we fished with lighter tackler some good size Atlantic cod up to 20-25 pounds that in it's self would be a great trip.
Around 7-8 I nth afternoon we got the first bite on the shark rig I strapped in to the harness and buckled up the reel.
It's not like fishing the kids of sharks you catch in the us their slow but strong, after fighting ardor an hour we got the first glint of the shark it was around 350 pounds real ugly bucker tab.
But still felt great that we actually caught one about 30 mints later my dad hooked one up on his rod it took him almost 2 hours to get the beast to the surface it's the biggest creature me and my dad have ever caught being almost around 600 pounds.
Both the releases went great and hopefully they managed UN harmed from the long fight.
So now IM out to try catching some big ass sharks in the states hopefully with little bit more power and fight in them
