Alright boys, I just set them up and took a couple of hill runs, and let me tell you... THESE ARE FUCKING FIRE.
On rough asphalt they retain speed and they grip like crazy. They even feel stable going over chunky asphalt on the street. I was able to pump for speed downhill pretty hard without sliding out. Usually with the 99a F4's it feels too icy on rough asphalt and I break into a slide if I pump too hard. The 97s have a much more controlled slide compared to the 99s, and it feels fantastic being able to hold a powerslide on the 97s.
On smooth concrete they still grip pretty nice and gives out a low pitched, classic sounding wheel bark when sliding. Though the tradeoff with this is that you lose maybe like 10% of speed compared to the 99a F4's, but it's nowhere near as drastic as the speed reduction of nonF4 99a spitfire OG classics. It still feels like an F4.
I'm pretty sure these are going to be my new favorite wheel, I'm a little heavy footed and found 99A F4s to be too icy, but these 97s are perfect. This is only skating them for 20 minutes but they feel great out of the box.
Go buy some now.
