I am fishing for smallmouth in 20' to 50' of water and wanted to get your opinion/recommendations on which swimbaits to buy.The lake gets carolina rigged all the time and wanted to show them something different.The forage is; Alewife,Golden Shiner,Rainbow Smelt,
Blueback Herring,Yellow Perch,and White Perch.The smallmouth seem to favor the Rainbow Smelt and the Yellow Perch.The lake is rocky with grass (3" to 5") off the bottom which seems to be sparse.I have been catching smallmouth there c-rigging lizards but everyone is throwing them!I will be fishing this lake in the fall when they are deep.
thanks in advance :-)

Try the Mattlures smaller baits, I think he makes a Yellow Perch color.

3 inch Big Hammers on 1/4 oz. 1/0 or 3/8 oz. 2/0 Hammerhead Super Shad heads (The 3/8 oz. Super Shad is designed to fit the 3 inch Hammer - unlike other 3/8 oz. "tri-shaped" heads).

4 inch Big Hammers on 1/2 oz. 3/0 or 3/4 oz. 3/0 Super Shad heads.

Find the depth the fish are at and start with a medium/slow retrieve. You may want to "spruce up" the action every now and then with short pauses in your retrieve.

Last year we were at Lake San Antonio (water-skiing trip with a little fishing) and could not get bit on the usual stuff. My 8 year old nephew nailed a small striper on a 3 inch Hammer and for the rest of the trip we had some very good smallie (and a few largemouth) fishing using the 3 inch Hammers doing exactly what I described above.
