Best 1650 fw for DL burning?

Has anyone tested BCIC with DL discs (Verbatim MKM 001)? How does it compare to BCDC? Or perhaps BCFC or BCHC?

Just about every CD-DVD Speed & Kprobe post I see is for SL discs, but I burn almost as many DL discs as SL, so the info isn’t very helpful.

Maybe you can decide from these threads:
