Honestly there are nice fish in harties but I wont waste my money going to a place that if the wind blows in the wrong direction you cant fish.
The hyacinths is a massive problem. For kommandonek if the wind blows anything between east and north you wont be able to fish.
You can have 300-400m solid mat that comes in and makes fishing impossible.
Then you also have the problem of safety all of harties is a security risk. The 2 best places are meerhof and kommandonek but you are still at a high risk of something happening.
If you can live with the chance of not even being able to fish for a whole weekend and that your stuff could be stolen then a good mix of tigers, mielies and hemp as feed with a nice sweet dipped tiger peach/pineapple ens. as hookbait nice and deep 15-200m you might pick up a monster.
