Your swordgrass looks really good. The height is right for swordgrass that I have had the misfortune to survey through here on Guam. That stuff will cut you to shreds. You have to wear long sleeves and long heavy pants even though the humidity is near 90% and the heat is well into the 90s. Did I mention that it effectively blocks any breeze too? Yeah it is just a bloody joy - nasty stuff to run away from your enemies as well. You might want to have special rules about being knocked prone, tripped, etc. Plus after moving through it your trail will be very apparent for a day or two.
