Karma even though I have a noodle in the photo I have never used it at H/C. I think that any extra drag you add to the light will pull it down farther in the ripping deep current at H/C. Also weeds will start to gather on your line and ride down to the light creating more drag.

The large branch hanger long line clip shown in the photo is large enough to clip onto your anchor line; I sometimes use this set up and helps greatly lengthen my light field in fast dirty water nights. At H/C I normally shrimp alone and anchor into the current and not sideways like at OH. This set up allows me to put one light on my anchor way out in front deep and then deploy one light off each side of the boat. This gives me the best wide, long light field needed on fast dirty water nights.

However on most nights I try to use only one light on each side of the boat with a darker area in front of the boat. This creates the kill zone that funnels shrimp in on weaker tides. Also the weaker the tide the deeper I set my lights. I never want to see a bright spot in the center of my light field; if so the shrimp seem to spook and rim around it. I want the shrimp to just swim right through and not care about the lights below it for super easy kills.

I have many different size weights to ajust to the current speed. I may only need 8 pds most nights but can go up to 15 when the tide rips past 4 grand and deep in the channel.

I am working on a new rig that I can adjust the light depth without pulling my lights back in and re-adjusting the long line clip. Basically my light rope is a large loop and it attached to my locking carbiner clip at my weight. This point acts like a pulley and I can just pull on the rope and adjust the light depth to where I want it,  up or down without moving the weight. I still attach the weight with the long line branch hanger clip though. The only draw back so far is now I have two lines coming in and out of the water for each light and this creates more crap around my feet, more water drag, more weeds on my lines plus I have to use twice a much weight line.

Warning do not use a spring clip to attach your weight to your line.. I have not had problems but know people that have. Plus after mine sat all summer the spring became sticky. I now use a locking type has a nut that will not come lose and I added just a little anti seize to keep the nut workin freely.

Good luck.
