whats so bad about em??? i am just wondering because that is the pedal sam hill uses. unless he is getting a specialized rendition. which is very possible.
I think the main problem I found was the the 5050 is a flat solid surface so it is difficult for your feet to push down and grip the pins. If you look at a lot of bmx style pedals there is less material in the middle, the surface is somewhat concave so your foot can push down and grip the pins better and the overall surface of the pedal is textured to allow for additional grip.
While I love the performance of the eastern pedals I use they are little boat anchors on my bike. I have the 23oz set. There is a lighter 18oz set but I can't imagine it is a huge improvement.
