My buddy is prefishing today and he found a cove with alot of grass.  Going to throw some frogs first thing and other top water.   Any certain baits do you throw when you see grass?

matted or subsurface?

Now do you guys try to throw all up into the grass or on the outskirts of it.  Im guessing if your throwing into the grass you need heavy line.   Set up?

When I'm throwing into thick matted grass I ALWAYS use braid. I also use a 7' 3" - 7' 6" Heavy action rod with a high speed reel. But that is my own personal preference.

If it's matted, I like to punch through with an appropriate sized tungsten weight and a small plastic. Something like a BB Cricket or an Ugly Otter. Rage craws and baby rage craws are really effective as well. If I'm working the edges of a mat, I'll use a frog in the mornings on the sparser grass then switch over to something like a swim jig as the day progresses.

As far as line and gear goes, I use 30lb to 40lb braid, other guys use heavier. If the fish are being finicky, I'll tie on a fluoro leader.  When I'm punching, I'll use a decent flippin stick no leader. On the outside edges you can get away with almost any rod, as long as it's got some backbone to stop the fish from turning into the grass. Reels are personal preference. I've got a 6.4 and a 7.1 that I use around grass.

The most effective grass jig made is a Terry Oldham's Eye-Max Jig & is what I flip/pitch/punch grass.

Favorite weight depends on type of cover and denseness of cover
