I finally got around to watching this video... trying to figure out which duro he is skating. He said the wheels are quiet so I don't think its the harder ones.
The 97a (with core) were the loudest wheels I've ever skated... actually a bit too loud, but it was fun for slides. The 95a (with core) were fairly loud, but in a good way... reminded me of Bones 103a with a typical "Bones bark".
The 93a are a bit quieter and sound similar to a F4 99a in volume. Not too quiet, just a standard wheel volume. Meanwhile the 90a are almost silent when sliding, which threw me off.
He also said you can feel with your fingers that they are a bit softer... The 93a its softer to the touch but in a subtle way, the 90a is very obviously soft to the touch.
Those two factors are making me lean towards he is possibly skating the 90a (which feel like a cruiser wheel to me) in this video but its hard to tell.
I think the 90a are a bit overkill for street skating, and would just recommend 93a. However, the 90a wheels could probably unlock some absolutely unskateable spots. As he said in the video, it would have to be another wheel "in your quiver" because you probably don't want to skate the 90a normally. However, the 93a is absolutely an "every day" wheel. They work well for park, street, transport and feel unmistakably like a harder wheel.
The one thing I haven't gotten to try is grinds. The fact that he didn't have any problems with grinds (possibly even on the 90a which slide worse than the 93a!) is crazy. If that's true, these things are going to be a bigger leap forward for wheels than the STF/F4 were by a mile.
The thing he said that I don't know if I've underscored enough... these things slide well AND grip well. It seems like that is contradictory, but its true. I haven't slipped out a single time on the 93a and I've been skating these things hardcore for about 3 weeks now. I also haven't gotten bucked by a rock a single time either. He said the wheels turned a really slippery park into a normal slightly slippery park. I had the exact same experience with these turning a really slick blacktop parking lot into just a normal easy to slide parking lot.
I'm starting to feel like a broken record but seriously, these 93a are like a dream wheel to me.
