Swamp cypress planks look a fair bit similar to jungle planks, to where it can be hard to tell them apart at a glance. I feel like they miss an opportunity to stand out from vanilla plank offerings as they are currently. Unfortunately, I'm not quite sure how I would adjust them to make them distinguished.

We're aware they're similar, but we don't see this as a problem. You can mix the two and create subtle patterns, great for small details.
