I scoured the various brands and wheel options out there looking for the perfect wheel for cruising around the rougher roads and sidewalks of my neighborhood. I knew I had to go with a bigger diameter, and fairly soft as well, but not too soft. I still wanted some long rolling time. Eventually I settled on these 85mm 77a wheels, and I am so glad that I did. I used to have 72mm 82a wheels. Going down the sidewalks uses to be quite a chore, going bang bang bang all the way along. Now, the ride on sidewalks is just a softer thud thud thud, and I am able to roll without pushing for easily three times the distance as before. If you have rougher roads and ride a bunch of sidewalks, these are the wheels for you without a doubt. Grab a set you will love them. I bought mine with the Zenit brand built in spacer bearings, and I am extremely happy.
