BenQ 1620 White tray or Black Tray

In B7W9 MCC 003 are rated @12x.

Thanks crossq: It look like I might be in heaven with this BenQ 1620, it overspeeds all my media without MCSE, but I will try TYG03@ TYG02 even though they both have 16x option. I find it wierd that the more expensive TYG03 doesn’t write as well as TYG02, I have found that in other firmware also.
