Way too pricey!!!!!!
Especially after you lose a couple in one night.
There is no need to have such heavy hardware at the end of the 6/0 you want to buy. You'll run what, 50#? Fifty lb running line with 600 lb on the end. Nope, too big. Just get the circles in my link, some 250# mono and #12 Malin and make your own. That will bring in whatever you latch onto.
I'm running 85# on two and 100# on another and the biggest I go is maybe #19 Malin, normally 12-15. Hooks up to 20/0.
Save your money for some good drinkey-drink and ceegars!
