I used to do that on my main in COC with a 4 x 12, a 6 x 24, and a 8 x 36 due to the wider variety of NPC capacities. The last of which was almost exclusively used to turn Cinnabar into a Sparrow art.
In TiTs, Most NPCs seem to max out around the same capacity anyway, so I mainly stick to a basic DBP combo. I also prefer the aesthetics of a single set herm.
