Tie it directly to the hook, The point is to have as few knots as possible in any line and knots along with swivels take away a natural presentation. IN
super clear water, yes power pro will spook them, but in the sticks, I would imagine tat the water will be slightly murky and this is where the line will excel. I would stick to 20 or 30 lb line, but I have gone as high as 50 and have seen o difference in hit ratio, but you better believe, when you set the hook on them with 50, you will come close to jerking them in the boat with you if they are under 3 lbs. I saw my dad kill one doing this because he jerked the fish out of the water and it slammed ito the top of the trolling motor. Just remember, sometimes less is more when fishing the worms.
Good luck and tight lines,
Brent
