I don't understand the difference of this suggestion to the available
A-100P6.

That's kind of the A-100PMB (monster base) and a A-100PMS6

We have already so many different types of A-100 cases available (A-100G6,
A-100P6, A-100P9, A-100PMS6, A-100PMS9, A-100PMS12, A-100PMD12, A-100LC6,
A-100LC9, A-100MC raw, A-100MC black) and I don't want to add new versions.
Especially for our dealers it's a big problem to have that many different
versions of A-100 cases in stock.

Best wishes
