Well , I've had nothing but good luck with MCC004 and BSPB firmware!
I bought 2 25packs about two months ago and I've tried LB, OB and now PB with it.
I got 97s with default LB and OB , 99s if I changed the strategy to TY T03 but now default PB gives me 99s
Settings are always
SB: On for known and unknown
All discs are burned are 12x
I would upload some scans but I didn't save them and I gave the discs to a friend. Maybe later when I burn something new
