Since our bowling performs most days I'll have a cutoff for averages above 30 and less than 20 games (keep an eye on joe paris with a bowling average of 19 after 6 games and 20 after 15 list a games though!)

Cummins: 29.84
Ahmed: 29.76
Tremain: 29.31
Coulter-Nile: 28.97
Mennie: 28.79
Henriques: 28.00
Bollinger: 28.00
Siddle: 27.91
Fielding: 27.92
Mitch Marsh: 27.55
Cutting: 27.49
Hastings: 26.57
Starc: 26.5
Behrendorff: 25.45
Hazelwood: 25.05
O'Keefe: 24.79
Chad Sayers: 24.69
James Pattinson: 24.63
Faulkner: 24.26
Bird: 23.77

Based on this you would have Bird Faulkner and Pattinson (maybe swap starc for one for the lh variety and the fact he is improving so quick) with O'keefe as the spinner. So maybe Faulkner Bird/Pattinson Starc and O'keefe as an attack
