IMO Both fairly flat/low entry rocker and catch waves early and good for crowd killin and for planing speed in weak/soft waves and zooming around sections.Why? And why not Darkness?
If you’re considering both around the same length, I’d look at it like…
Plasmid: chunkier tail with bonzer-lite channel is better for turns. Can be surfed more aggressively from the tail.
Dankness: glide for cruisin and swooping carves on shoulder. I surf mine more from the middle than the tail, as use it as a mini miniglider
