Well, both CA bats and the BAS bat I have are nice bats. Have an AS on the way, as I wwanted to try one out. Never used an SS but everything I have read suggests that they're decent enough!
And as much as I like the CA and BAS bats that I have, I would still use a Redback, Laver, Screaming Cat, Salix or Newbery ahead of them!!
That's personal choice, as I personally have found that the balance, the control, and the quality to be slightly better.
Picking just one of those brands will be your hardest choice mate! The only choice I would question is the Redback, as you have listed the Surefire?
Batting number 7, I would tend to opt for the more all round bat - the Allegiance? Or do what I did and go for the custom made 'in-between' bat?
If you look in the Bat Review section, you'll see the review mate. I haven't done a review of my Screaming Cat yet, but that bat is likely to be as awesome as the Redback!!
If I had to buy just one of those bats, I seriously wouldn't have a clue of which bat to purchase! But keep us all updated!
