Confession time. I just like shaving with straights, and I'll take a straight on my face above a Mach 3 any day of the week - this might sound girly, but the straight is way easier on my skin. I also shave my head, and even there, the straight does a better job - but only going front to back. The other way around, I have to fall back on the Mach 3, and it works well! Finally, I sometimes touch up and trim around the, uh, intimate zone, and refuse to put a straight anywhere near it! This is where the Mach 3 does its very best work...!
