Really like how the Premium shape feels; big wide body, super thin, enough concave, light as hell. No bent spindles from riding em since last fall, but I'm a peg grinder.
For the sake of clarity, I picked up a set of the plastics on the cheap. They feel great, but $100 for a pair of metal pedals (BMX pedals are a relatively high wear part) is still extremely expensive. If you're going to pedal grind, definitely avoid them.
The lack of wrench flats is a bit of a hassle, but not a big deal. Makes it slightly harder using an 8mm Allen wrench, but installing them wasn't a deal breaker. I used the age old G-Sport advice and shouted, "STRENGTH OF A BEAR!" as I turned the 8mm and they went right on.
