Based on the information available many would agree that the idea line size for Spybaits is 4-6 lb test for the Duo Realis 80’s and some use 8-10 lb for the 90’s on casting reels. From what I read most are saying to use the smallest diameter line you can get away with so your line doesn’t hinder the action of the bait on the fall / retrieve.
What I am wondering is has anyone tried fishing them with a loop knot? I feel like you can maybe get away with a higher lb test using the loop so you get a little more security in line strength without hindering it’s action. Any thoughts on this?
