ok just to clarify, the reason I wanted to go clipless is efficiency not for the trend. Maybe it's placebo but during the uphill ride I really do pull up the pedal and I find that it makes me less tired to cycle this way. I hear some people say that noone really pulls up but I have seen me do it .

Also others are mentioning how the unclip procedure becomes second nature. And it has for me as well, BUT only if I am riding on an even surface. I have a very hard time unclipping whike i am riding uphill, the foot just doesn't come out and I have to try many times. It's just the angle that makes it difficult. Also the power applied to pedal to move forward seems to be directly interfereing with trying to twist the ankle , sometimes I feel I am bout the fly off the bike doing so. And I don't want to make the cleats more loose because I understand that htere is some danger when the foot comes off too easily.

So is there a special trick to disengage when in an uphill angle?
