I'm sure they're fine, everyone likes different shit. I skated a set of STF's about a year ago and I just didn't like them. I gave them a solid month, during which I was skating and taking public transit everywhere. They felt like I was skating rocks. I didn't like the way they slid. They were loud as fuck. Every time I hit a sidewalk crack I could feel it in my teeth. When I started skating in the early-mid 90s, anything Powell or Bones were considered lame as fuck amongst my peers, so it took literally 20 years before I even skated a set of reds.
Spitfire's feel right. Classics or big heads for 20 years will do that.
I can't believe I seriously answered Tracer.
