Don't fret the single barbless hook. As long as tension is kept on the line - fish not likely to get away.
I had no trouble last year with fish being missed due to single hook. No matter what - some miss the strike. A 30 inch Rock can eat a 2 lb Shad - a little 9 inch lure is an appretizer to them.
I'm planning to run one board with 5 rigs - 3 tandem and 2 singles. My idea is to imitate a bait school. Starting at 100 feet of line and working to 60 feet off the clips. Staggering them about 10 feet.
1 umbrella off the corner back 200 feet rounds out the 6 rods. This will get adjusted to where I see bait or thermocline. Unweighted up to 20 ozs of sinker.
If the outer shallow singles get hit - then I'll adjust and put the other board over. The 6 rods makes it slower to figure them out. If over fish and no hits - try swapping shad colors , moving lures , etc.
I've found most spring Rock fairly aggressive to hit - once over them and current moving.
If you miss 3-4 fish - it often helps top bump speed up ( yes , faster ) about 1/2 knot or so.
