Hey guys! I've been reading your posts and I might be able to help. I fish blue marsh probably 3 times a month and rarely get skunked. No doubt it is a tough lake, but you can definitely catch them. Fish your strengths whether it be slow with a Texas rigged worm or cover a lot of water with a crank bait. I like to fish main lake whether its crazy with weekend boaters or not. I target smallies with spooks, poppers, crank baits, lipless crank baits, jerk baits and Texas rigged plastics. Depending on the time of year dictates what I do. But no matter what I begin the morning always with top water. When that water temp hits 45 degrees the top water starts for me. Fish main lake flats , points and bluffs with poppers and spooks. While throwing a spook there is always a great chance to hook up with a striper on top. That is a blast!! If you can't take the boat traffic on the weekend your best bet is to get out early or go during the week. No point on fishing for the smallies in the dark as they rely on sight for hunting prey. But first and last light you should be throwing top water. Or you can fish the no wake zone which you will find predominately large mouth territory. There are a lot of stumps lining the banks back in these arms so crank baits, soft plastics and spinner baits are great choices. As the guy earlier said you sometimes have to just grind it out but there are some real quality smallies in this lake. Hope that helps guys.
