I would say that if you have other boards that seem to work, you don’t need to be too too worried about this one stinker. Just get rid of it. Make note of the dimensions and take some photos beforehand, and use that to eventually figure out what exactly didn’t work for you. I keep a document in my notes app with my impressions of all the different boards i have owned/ride/borrow/rent etc.
On a different note today I went to one of my local spots and found a super rare occurrence: recent sand replenishment actually made it work *better*, not worse. Who knows how long it will last, but at least it’s fun right now
