All of it depends on the conditions and what the bass in that lake want. vague, i know. let me explain. i use different rigs depending on what lake im fishing and the conditions. for purple worms, i mostly just texas rig it with a sliding bullet weight, usually no bigger than 1/4 oz. using senkos, i either texas rig them weightless or wacky rig them. one lake i fish loves a wacky rigged senko. another lake i fish seems to prefer the senkos t rigged. on hot sunny day, i usually fish t rigged worms near wood or bounce the bottom. the bass will tell you what they want. Prime real estate for shore fishing is drop offs (usually they are parallel to the shore line). i try to throw my lure as parallel to the shore along the drop off as i can. that way youre in the strike zone longer. look for any kind of structure. structure can be sunken wood, a bowl like pocket in the lake bottom, weed lines, docks and rocks. if you see structure, HIT IT! if you look at my profile picture, you may notice the dock railing behind me. this dock is long with access to shallow and deep water. these kind of docks are great for finding fish! you can drag your bait parallel to the dock looking for suspended bass under the dock. you can cast shallow to deep looking for bass suspended on a drop off or weed line. then you can though deep diving cranks and worms to fish for the bigger fish in the deep. i've actually out fished friends on boats from the shore before. get out there, you will learn alot. I saw schooling bass on a feeding frenzy annihilate my lure the other day. while i was pulling my hooked bass in, two others were chasing it! weird but cool nonetheless. Good luck
