I would remove Munro from the equation unless you do not rate the bowling attacks they are facing this round and if you possess no bowlers from those lineups. Throughout all editions of the BBL, the Scorchers have been the premier bowling lineup with many a titles won on the back of that strength and their ability to defend low totals. Therefore, I am much more confident in selecting two or even three bowlers from the Scorchers in comparison to all other teams, in which I prefer a mixture of one from each position (bat, all, bowl).
Tye and Behrendorff are very difficult to seperate and even moreso with Mills already selected. This will come down to when you expect the wickets to fall during their double round and to whom. If you expect Mills to take the bulk of his wickets at the back end and eat into Tye’s production whilst not possessing many or any of the opposing openers. If you like the safety of the surge and death overs and expect Mills to be more potent at the start then go for Tye.
I would also factor in which player you would prefer to keep throughout the remainder of the season, in which case I would expect that to be A Tye. As for Zampa and Paris, thankfully no price movements will occur this round so you can take care of the other next round via dual position players to increase your options of which there should be value aplenty.
