I understand the "sticker" game that pros play. It is possible that pros using CAs maybe just putting stickers on bats made by other batmakers.
But...
And, there is always a but...
Having owned CAs, Keeleys, and Kranzies, I can tell you that top bats could be swapped out for another and, in terms of performance, you wouldn't know the difference. CAs are amazing bats and the ones I own slightly edge out my Keeleys - just slightly.
CA prices have risen a lot. You can still find great value but you'd have to hand pick bats from a big batch. Which is why, knowing a good dealer helps.
Ihsan bats are very under rated but they have awesome ping, you can get good prices. AM is a great value as well. You'd be lucky if you can land a MIDS - they are just plain awesome but also very pricey
