Pick up Boland, IMO. Opening batsman/keeper. Theodore, it might be worth opening the bowling with a spinner. Could work - Take the pace off the ball..
Pick up Dave, IMO. That way we have Kovas, Orr, Charles and I who can bowl, and then there is you and Herd.
We don't have Orr. We have Oz. I'll probably go after Dave or another batsman and just see if I can pick up a decent 5th bowler, or maybe just stock up the batting and bowl a combination of myself/AVA/Bender.
Eventhough it is T20 I wouldn't say going in with 2 batsman as named bowlers would be a great idea when there are plenty bowlers left.
