I've got shimano pedals (and I remain neutral as to which pedal to get, these are all I have experience with) and I backed off the tension screw on the pedal to make it a little easier to unclip. Same motion, just a lot more forgiving as far as getting my darned foot out. You do have to remember if you do have them too loose there is a chance your foot could pop out when you pedal which can cause ouchies. Once I got used to getting my foot out I brought the tension back up. That and grassy areas kept me from getting too banged up. I should have tried fields of goose poop-I bet I would have learned faster!!
I used to have an open mind but my brains kept falling out.
