Skated the new 97 at another smooth park. Just some observations:
-They don't bark much, I recall the 93 being louder. Just sounds different at first but I had no problem reverting or breaking into a power slide.
-Speaking of sound they're obviously going to be quieter. They sound less bouncy/soft than the 93, but aren't a 99 or 101. Personally this doesn't bother me.
-I didn't get any squealing or grabbing. I was skating X99 at the same park last Summer and had frequent annoyances with wax levels and grabbing/squealing. The coping was pretty dry when I got there today so it was a good test.
-Didn't notice any issues with speed compared to my 99 Radials. These are newer/larger, but less contact area.
So far they're a soft wheel I could leave on and not have any issues. I do think I like the feedback, sound, and overall feel of a harder wheel, but I also like pushing less and carrying speed a bit more consistently. One added benefit is our park has cracks before a lot of ledges and some sections where the crack has broken and it can mess up your pop and landing sometimes but these rolled right over it no issue.
