A few of my friends has got some good size Kobs at the Rasper , Od crackers have been around , i would Strongly advise you to Go fish Die plaat , with the water is Reg ,and it should be cos of the wind ....
You can also take the drive to De mond, go cast in the surf ,livies ,there plenty ,and the Elf seem to be there always ,nice for livebaits .
other spots you can try is Deurloop , Crackers and kobs ,T hak .
if the Kobs are around at stinkbaai like Galjoen said the you can Fish die las or die brood , or Skulpies baai there by the pipe at night Big Cobs come out .
take extra sinkers you tend to loose alot around places like die las and stinkbaai ......
Go to Bait and more , they have maps with all the spot on !
