First, let me say once you learn how to fish grass, you look for it and seek it out where others do not. You don't need mats, thicker subsurface weedbeds will work. I would look into a H action rod, 7'6" or better, no less then 30lb braid, no leaders needed, and tungsten weights or punch jigs....I suggest looking at Siebert Outdoors website and look into his punch jigs. Find you some beaver/craw baits, bobber stops and some strong hooks and your set.
Now fishing the grass you only want to use enough weight to get you thru the grass. I mainly use 1/2 to 1oz depending, like the Rage DB Craw as a trailer but that's me. Now, look at the grass, how it lays out. Look for where two kinds come together, where it has a hole, a thick spot, point, channel...etc. Look for irregularities in the grass. You want to let your bait fall on a semi-slack line(pay attention on the fall) and if you feel something that doesn't feel right or see it move, set the hook. Most grass bass you will feel weight when you lift up so you need to learn what your bait feels like and when it feels different. Once thru lift up and jig it 2 or 3 times and let it fall. No bite, on to the next spot in the weedbed.
I use this a lot in the summer on bright days when a lot of people choose not to fish or have slow fishing......not too many people punch the grass where I fish and use this to my advantage. I fish the sunny shores....why, because I know the bass are going to burry themselves up under the denser weeds and that's where I am looking to pitch my bait. Once you're bit, pull, steady pressure, no herky jerky. Just pull as you may have to pull a bunch of weeds in with that fish. They may fight or may think they are hidden. Be prepared when you remove the grass for that fish to wake up.
As spring turns into summer, watch the way the weedbeds grow, and any cover that may be in and around those beds are always great spots. Remember that anywhere two different kinds of weeds or cover meet is always a great place to try, and look for deeper water breaks close to the beds as well as if there are slight channed or bottom changes also. If there is a depression or hole under those beds, odds are there will be a fish sitting in it. There are quite a few articles on here if you look for them under grass/trash/weeds....etc. Welcome to punching, once you get a few you will be hooked, I love full contact fishing and that's pretty much what this is.
