I use a
headblade on the noggin and a Mach 3 Power for the rest. The Headblade is the greatest thing in the world to shave with once you get used to it, very few ways to cut the scalp (which bleeds like you wouldn't believe). Would never have purchased the Mach 3 Power (looked too gimicky) but got it as a gift for Christmas. I was surprised how well it actually works, I've not had any cuts or nicks since I switched over from the traditional Mach 3.
