Kyle Abbott over Morne Morkel. That's the choice former England great Kevin Pietersen would make if he was deciding who would replace injured bowler Dale Steyn.

Pietersen originally wanted Morkel in the Proteas' line-up for the opening Test in Perth, but believes Abbott is a better choice for the type of wicket that Hobart usually provides.

"I know I talked about Morne Morkel missing out – and he shouldn't have – in Perth, but that was (an opinion based on) conditions," Pietersen said.

"I think in Hobart, (with the ball) swinging and seaming, you need an areas kind of bowler.

"I think Kyle Abbott's your bowler – he pitches it up, gets it to swing a bit, bowls good areas.

"He'll complement that bowling attack really, really nicely, so fingers crossed the selectors go with Abbott."

Following Steyn's injury on day two of the first Test, South Africa only had two fast bowlers for the remainder of the match in Vernon Philander and Kagiso Rabada, given that debutant Keshav Maharaj was chosen ahead of a fourth quick.

South Africa's bowling attack shared the load in Steyn's absence and was a key factor in their victory, although a replacement quick for Steyn is a must.

Proteas coach Russell Domingo knows it's a choice between the pair, but he's yet to make his decision.

"We've got two options at the moment – Kyle Abbott and Morne Morkel," Domingo said.

"Morne is coming off a back injury. We'll assess him two days before the Test and make the call on whether he is 100 per cent fit.

"Kyle Abbott is a consistent, solid performer and has been every time he has come in.

"We need to weigh up what type of bowler we want to use under the conditions in Hobart, because I think they are different to what they are here (in Perth).

"It's a fascinating series because all three venues have totally different conditions.

"I've never been to Hobart, I've heard its cold and the wickets are a little New Zealand-like, a little slower."
