I also tried the V-O half clips and wasn't crazy about them. This was on a 50+ mile ride back in April on mixed terrain. I figured I'd need to get on and off of the pedals pretty quickly but needed some foot retention. The half clips did allow those two things to happen, but they were no easier to get into and flip the pedals (MKS touring pedals) than regular clips, and I didn't like how uncomfortable they were unless my foot was perfectly centered in the clip. You can just make out the half clip in the lower right and upper left corners of this pic:



Of course, ymmv.
