Sean, I caught a 35" and a 36" Red in about an hours time this past Sunday. I also had one that some how didn't hook up on a circle hook. I waded out waist deep and let 'er fly, probably 30 yards out. Counting down my weight, I was in about 8-10' of water. Be SURE you have your rod holders in the sand good, those fish will take your tackle if you're not careful.
I caught one on cut mullet and the other on crab. I saw one about 40" caught just down from me, it came on mullet.
I would recommend at least 6-8 oz of weight unless you're there at slack tide. I fish the Galveston side of the pass, Gulf side of the bridge. The grass was bad, but after a couple of times reeling in, clearing the grass and recasting, I just left them out there. The grass wads up on the line but usually it's a long ways from your bait.
Keep the Lord in your heart and keep your powder dry.
