I still use clips & straps mainly ,cos Im too cheap to buy the pedals .Though I do use a pair of Shimano mtb stp shoes( still a cheap skate nz$30 off Trademe) with rather aggressive self made cleats , I just reach down & loosen the strap when required ,it becomes 2nd nature, but I can usualy pull out in a hurry if I have to, execpt last week I was draughting a truck, just for the hell of it & I tightend the straps extra tight , when I eventualy lost the battle to keep up with the truck, he shot through the lights on a yellow & left me with a red & the opposing traffic already starting to move ,I knew I could stop ok putting all my weight on the back & braking hard on the front , very impressive till I came to put my foot down, my foot wouldnt come out , you know the rest thats life I ,spose!!
