That's just heavy line, the drag is able to handle these 20lb. rockfish right?. I BAJAb SPECIALED so much that I forgot about thinking "IS THIS THE RIGHT REEL?" a long time ago, good price for true power.
For deep water jigging use Izor 60 solid if thats the # you want,it will get down there faster than hollow,plus its way cheaper. A friends got a 500yrd spool for $40 if you want it. I would go with 665 single speed,4/1 ratio a bigger spool than the 270/870 means you can wind up more line, faster too.
