This is an amazing thread, I'm handing out gnars like oprah.
Personally, I trim the bush and balls with some clippers, and brush up the base of the shaft with a razor when shit starts getting out of hand. I use the same clippers for my head/face/pubes because I know that if I had separate ones I would mix them up at some point anyway so it's not even worth the effort. Face first, then bush because even though I shower right after anyway it would be a bummer if the water broke and I had to walk smelling balls on my beard all day.
