I always dug my Crank Brothers Egg Beater pedals. 4 sided entry, lots of float (easy on the knees). Super light weight, too. I've seen plenty of people with Speedplays too. I think Egg Beaters work with SPD cleats, so you may not even have to change those. Lots of good options out there, though.
Just work on your trackstands and you'll never need to clip out at a light!
