Two-sided pedals are easier, I think. I rode the Shimano M324's for a while, primarily for mountain biking. I finally decided to move up to the M540's (I think that's the name) and they're actually easier. They also work better than the Performance brand in the same style.
A lot of folks cut out the rubber around recessed clips, but I'd hate to do that.
And remember, watching a biker go down because they can't get unclipped is a priceless MasterCard moment. Think of the joy you bring others. I've certainly given the world a few chuckles.
One other thing. You can adjust the release pressures fairly easily with most brands. Mine were set so low for a while that if I sneezed hard I'd clip out. Give that a whirl.
