Hey everyone! I'm trying to get the knack for using umbrella rigs at San Antonio Lake for stripers and I am wondering if anyone out there uses them regularly. I've been using 8 white 4 inch tails with a half ounce hair raiser jig following on a 2 foot leader. I've added some 4 ounces of weight just ahead of the rig and put the whole thing back behind the boat about 150 feet. I've not had much luck with this despite trolling several days in areas with good bait. Any help would be appreciated!
