What to do?

[basstech]

It's been over two years since I've been skunked back to back outings. I know the lake pretty well, at least all of the major features and many smaller, lesser known important features. A guy I work with and I have been fishing together for nearly 8yrs. now and we started fishing the little local tourney out there. I caught one fish the first tourney, had 19 boats and 7 fish brought in by 6 boats, actually, five boats and six fish cause ours did not count being that I didn't put the mark up on time, my bad, the rules are the rules.
Anyway, that last two weekends we've blanked. He caught a small wiper last saturday and that was one of only two bites we got all day (the second one I missed if it was even a bite, not sure). The Lake is around 680 to 760 surface acres. There are two parts two it, the main lake has trees in the two largest coves on the north west side of the lake. Both have a major secondary channell feeding out to the main lake. It also has a flat that get's very weedy with coontail. There are plenty of rocks as well. We've fished in there most of the time and haven't caught squat niether has anyone else that I know of. The back half of the lake covers Old Wood's Chappel road and the old roadbed is only about four foot deep and then drops off on the left or east side of the road...there is no drop on the right...it is flat up to the bridge. Also back here is the main channel that runs 20ft deep and I know of a secondary channel comming in the farthest reach and the whole area consist flooded timber, It's probably 300 surface acres in size. We've thrown everything and fished hard to get blanked....We've worked Exceedingly slow at times placing our cast two feet apart and taking 5 minutes or more to work the lure back per cast. We've fished at a moderately slow rate somewhat steadily moving. We've fished in very deep (for this lake) 30ft. up to 2ft. flats. Thrown Various colors and size's rogues (used suspend dots to get them neutral. Adjust slightly to make them rise or sink very slowly, like a foot every 20 to 30 seconds. Nothing. Spinner baits, Hvy. with single colorado #4 silver. Carolina Rigs. Deep diving cranks. Jig and Pig. The following baits on a 1/4 oz or 3/8oz. Standup Jig head, Super Hawg, Skirted Twin grub, 21/2" yum crawbug and 3". On a spinning rod with a 1/8oz. jighead I used flukes, tubes, and grubs. Any ideas on what we should try tomorrow? The last two weeks it's taken 16 lbs. on 4 fish limit. to win. The first limit weighed in was last week and the guy said he caught his fish in 2ft. of water on a white spinner bait. Water temp has been 46 steadily for the last 3 weeks, water clarity is anywhere from 5ft. to two feet. Closer to the bank, and shallow flats there is less visibility in the water and it has a light brown(mud) tint. The clearer waters have a green tint. What should we do tomorrow?
