As summer begins to set in, many bass will seek shelter and forage under various types of grass mats. But not all mats are created equal. Grass type, maturity, location, thickness, depth underneath and many other variables must factor in to your approach when targeting a mat. With that being said, I still see bass anglers (even really good ones) focus more on what bait they’re going to throw at a mat than what weight they’re going to use. Huge mistake. As far as I’m concerned, the wad of plastic you pitch needs to be roughly three inches long and have the ability to penetrate the mat effectively over and over. That’s it. Criteria met regarding the lure. Pick any color you like. Choosing a weight, however, is actually more complex.
