They are catching many fish out east of chatham with them. Most of my fish this year have been on a brown/grn splash bar long rigger. You can run them really far back. They work really well on the smaller boats with low riggers.
If you mean replacing the first squid on the outer lines,yes,it works pretty good.Leave 3/4 or 1 inch of room for the bird to work,dont crimp it up tight to the bar. The spray cans meant for plastic lawn furniture sticks pretty good if you need "custom" colors.
Just started fishing splash bars in the last few trips and have gone 3/6 in hook ups. I never before fished these kind of bars until I fished with Capt. Eric Stewart on the Tuna Fever. He made me a believer in these bars. I am able to run them farther back on my riggers and the stay up on the water better.
