"That's going to be the million dollar question," Arthur said when asked whether the Aussies would go for a two-pronged spin attack in the Test starting here on March 2.
"It's easy in hindsight having a look at how the wicket ended up, you probably would have liked two spinners on there, however, our quicks took most wickets. We didn't get a massive return from spin in this game. I thought James Pattinson was outstanding, so it's a difficult dilemma," he explained.
"Looking at the way it ended up probably two spinners (would have been good) but our quicks were the most likely out there, so I am not sure which way really," he said.
Xavier Doherty is the second spin option for the Australians if they decide to go for more than one slow bowlers.

"I think on wickets like this balls turning into you are just as effective, because you've actually got to play," Arthur was quoted as saying by 'ESPN Cricinfo'.
Arthur said the opening Test was a massive learning experience for the team's only full-time spinner Nathan Lyon, conceded 244 runs for four wickets.
"I think he has learnt from this game that you have got to be really consistent in conditions like this in order to put the batsmen under any sort of pressure, but I think he will grow and he will learn from this game," Arthur said.
