It all depends on how good you can play at your home and get a win or 2 away from home.
I like the Joburg Super Kings as they have players to score fast especially up on the Highveld. Would be great matches especially the one against Paarl imo.
Coming to Pretoria if they produce juicy wickets I like their chances as their bowling is good if it is flat wicket then their bowlers might go for a ride.
Paarl track will be flat and might turn in the last 2 games so I expect those to be high scoring games and also expect Paarl to lose 2-3 at home especially at the beginning as I cant see their bowling being able to contain the opposition at home
Durban have a great team but if you ask me it will be the easiest place along with Paarl to get away win for any team as wicket will be flat and short square boundaries I am expecting the biggest chases to be here and Joburg but expecting more success for away teams here as Joburg bowling a bit more tight compared to Durban
SEC will have the lowest avg score of all the wickets imo unless Pretoria produces juicy wickets tailormade for their bowlers. So expect low scoring close encounters here and SEC have a good team who know the conditions well.
MI CapeTown I expect will create just good T20 wickets coz they have the best and most experienced T20 team so they wont have any surprises at Newlands they will be tough to beat as their bowlers will just do what they always do with Rashid leading the line and expect their batsmen to score well with their mighty middle order
