I've had varying success at Mpenjati over a 15 year period, but have had some decent bigeye kingies further unpstream. Lately I have reverted to dropshot / softbaits as I can cover more water. I hope the estuaries are fishable - there has been a lot of rain down there lately. PS, have had some small kingies and the odd snapper in Southbroom lagoon too. I use an ark to get around both of these venues...Good luck.
