Before you fill a module full of stacked cables, think about how much torque you'd apply if you accidentally bumped that stack with your elbow. I'm thinking of getting some short male to female cables to lesson the worry. I tend to limit my stacks to just one piggy back. Stackables have taps at both ends, so you can split at the output and the input. Anything more than that, I reach for a proper passive splitter (Intellijel makes nice ones with magnetic backs). I'll only split gates and triggers. Anything that's going to note pitch, I put through an active mult.
