Fishing the Upper Potomac you only need a few lures.
Shallow crankbaits in crayfish #1, shad/white and firetiger/chart. I recommend Bandit 100's as they are cheap and work well.
For soft plastics; Zoom baby brush hogs in green pumkin, black and maybe watermelon candy but I fish the first two 95% of the time. Senkos; watermelon, green pumkin and the Kinami natural shad color really work. Zoom flukes in pearl white or Albino work around grass and in shallow water. Just watch out because the Muskee like them.
Topwaters; Heddon tiny torpedo, Jitterbug and a white buzzbait. In the fall jerkbaits and I use Lucky Craft which are expensive but a Husky Jerk #8 in Silver works.
