I'm a DE shaver from SMF that migrated to straights. You might be surprised at how efficient a straight shave is. My DE shaves tend to run 15-16 minutes, and the last few days my straight shaves have dropped substantially below that time. The main thing increasing the time of a straight shave is the stropping, but this is compensated for by the wider blade (requires fewer strokes), and less rinsing of the blade (straights don't get clogged). Also, I've gradually settled on only two passes with the straight. That third pass against the grain gives me a better shave, but it's also a 2-day shave and that's not as much fun :-)
