Have you been able to run some comparisons? I can think of a lot of ways to make a home tumbler, but I also had occasion once to buy brass from Jeff Bartlett which he warned had tumbled a little too long, and all the case mouths were turned inward and required expansion. I have also seen at least one photo of brass with the surface clearly stippled by stainless pins, which undoubtedly fell too far in whatever tumbler was involved in that cleaning.

So I suspect there's an optimal combination of drop distance (affected by drum size and rate of rotation) and number of falls (also affected by rate of rotation) for best compromise of cleaning and brass handling. I just don't know where those limits lie, exactly (hence my recommendation to stick with the known quantity). But if anyone can show other working combinations, but all means reveal them.
