LH-20A1p Firmware advise

Just ordered one of these to replace my 165H6S, burn mostly Verbs and TY to backup movies.
Also will use for scanning with CD Speed.
What firmware is best? I am not worried about speed but rather quality. I usually burn at 12X.

The current firmware version KL0N works fine for me.
It does a good job with TY, MCC and most other 8x and
16x media.

I got mine yesterday, came with KLON, did 4 burns so far, I am going to try CK’s patched firmware this weekend, looks real good from what I have read.
