Maybe Fran could enlighten us as to the sound difference between the bk5 and bk7m. After all...He started the topic to revisit the bk5. A comparison is a relevant question.
Many folks have said there is a difference in sound..
I have never A-B'd them... but I have A-B'd the same name styles from the BK5 and BK7m... they are revoiced differently.. Maybe this is what folks hear.
