I'll rate the CA bats when I've had a chance to look at them and have a hit with one, the ones I see are very good but also pricey, they have a similar trade price to the big brands here so if you are getting a CA cheap it may be faked. I've gone down the blank route as the bats will be of the very highest quality but the price is a lot less.
I had 10 AS bats last year, they were a pleasant surprise, they were big and ping'd like mad, not pretty or well finished but value for money.
