Not only do I ride from spot to spot but I also ride my skateboard to and from the train to get to and from work. Because of this, even though I like I like super hard wheels, I got the 99s in the classic shape and 52mm.
Holy shit! First of all, these things felt hard enough for my liking, but not "rattle your teeth" hard. So far I was glad that I got the 99's.
There is a slight angle on one of the streets going to work, resulting in a very tiny hill. I was cruising down that hill and decided to test these wheels out and went for a power slide. I wasn't sure how easy they would slide so I put A decent amount of pressure and they slid instantly like butter. Not wanting to slip out, I eased up and straightened my leg out and the wheels instantly stopped sliding and went back to normal.
These wheels exceed the hype of sliding when you want them to and gripping when you want them to.
No I can't say about the longgevity of the wheels, I've only had them for a few days, and I can't comment on the 101s but the 99's, so far, are the best wheel I've ever skated.
Edit: here's a picture of them fresh. Bonus: fresh deck as well.
