I think 90 is my favorite even though I’ve never used it. 83 feels too small for me and 97s are a bit big. I have a feeling I’d love 90s. If someone made an Evolve gt style wheel in 90mm I’d buy it instantly.
I have Enertion 83mm wheels and Orangatang Kegel 80mm. They are both nice wheels but the Orangatang’s are much nicer because they feel smooth and much carvier than Enertion’s. A good way to test for me was the rebound of the wheels. The Kegels bounced high and Enertion’s didn’t bounce at all. This is probably the hardness of the wheel. I think 90mm would be nicer than 83 because a higher speed and better for not getting stuck on things,
