I personally don't like fangs as when the bumper drags on the ground during a nosedive it slows the board down quickly, when I first nosedived at 3k miles the friction caused me to slow down to about 5mph before I had to run it out, I was going downhill and if I had fangs I would have continued accelerating, eventually you need to bail and with fangs wouldn't have been able to run it out.
I have these. Not sure if they offer a false sense of security or not. But, to me, it increases the chances of me not having a catastrophic injury. I also don’t try to go 30mph downhill without protective gear. Full TSG Pass Pro helmet & wrist guards. Still fun.
I put these on mine and love em. They work well and prevent exactly what's being described.
