yup yup yup, you need to use square billed cranks or coffin billed cranks. i have found that square billed work a little better for bouncing off stuff.
two great lures to invest in are: Rapala DT Fat and Rapala DT Flat.
the fat has a square bill and its a very fat bodied balsa lure. the flat has a coffin bill and is a very flat bodied balsa lure.
a nice sensative rod will aid in the crashing technique, for the sole purpose that you will know exactly when you hit something. when you feel the bump of hitting something, just stop, and let your crankbait float. if you know there is very little chance of snagging the object (like a smooth rock) then you might even want to jerk your lure forward and then stop it.
what i do is i will run my crank into whatever is around....the bottom, stumps, trees, rocks...
but i try to stay away from brush. brush (at least my interpretation of the word "brush) is like a bush w/o leaves...tons of thin scraggly branches shooting out in all directions. since this isnt really a very "solid" target, there is alot of open space between the thin branches, it is easy to snag in. when im fishing brush, i will usually either put the crankbait down and pick up a worm, or just fish the crank around the edges of the brush.
you will get snagged a lot less if you hit more solid targets like stumps or trees (that dont have tons of scraggly branches) and rocks. the cranks will just bounce off to the side of these.
bottom line is just keep things erratic. this is what will keep the bass interested in your lures. most pepole will be mechanically dragging their lures in open water for fear of snagging.
dont be like other people...fish it in the nasty stuff where the bass actually live
hope this helped....GOOD LUCK!!!!
