I really love my ATACs, but I have been using GR-9s (with clips/straps) for awhile now. It is kinda nice to be able to "clip-out" by pulling backward when I ride my local area. I tighten the straps as needed.
I tried clips again this weekend, because I didn't want to bring my bike shoes for the trip, and it sucked. I'm so used to pulling on the pedal in all different directions with clipless that I kept pulling out off the pedal with the clips =P
That doesn't happen to me. I do very well with clips; I can yank the crap out of it without worrying about float-angle. ... Problem for me would be to find a right pair of shoes, though. This is the uber-turn-off for clips for me.
