I don't see how riding these super loose trucks is good for anyone.
I do dislike the fact that when I'm going to fakie, I gotta land just right or I'm fucked.
But, to me, that's worth the stupid wiggling that I can do. I can't explain how satisfying it is to just do little movements that I couldn't when I had average trucks. Counterintuitively, it also keeps me on my board more because there's more room for error when I land, especially since I'm a klutz. I also don't really do many tricks outside of ollies, halfcabs, and 360 no-complies.
I certainly don't believe in the cult of loose trucks, I just like to ride things because they feel good to me.
