I have found large amounts of shad .However there are pods of super small or huge shad. Some of the shad reach six inches or more. On my lake stripers get healthy . I have seen blow ups but its hard to match the hatch. Am I waisting my time or should I pick apart isolated cover . The spots are crusing and I have had some luck but without a boat I am jumping around.

LMB doesn't normally chase like Striper.  They're more like ambush fish.  If you found the shad, it doesn't necessary mean you found LMB.  I would sonar the area and check for cliff that have humps or veggies.  If it's a flat, it's usually some kind of structure that they will tend to hide in to ambush.  

 

Usually in the morning/evening when the sun is not out, they are at points or cove.  Later in the day when the Sun is up, they will hide in grass/tree structure by the shore or they will jump down to thermocline and ambush or just hide away from the sun.
