Got myself a set of those spitfire 93a in the conical shape.
First impressions:
When comparing spitfires 93 and dragons, the only thing they have in common, is the number printed on the wheels.
The spitfires feel way harder and rattely, almost like a normal wheel. I cannot believe that these wheels are supposed to be 93a.
Good slide and overall feel.
I'd say crusty spots -> dragons/x formula, old parks/medium crust->spitfire 93a
