why 1/160?
I agree about shooting in manual mode, but use whatever f/stop - shutter speed combination works for that particular situation.
You're right. However, for me, from trial and error, that's usually where I start. f5.6 gives me pretty good distance for my flash (420EX) and a decent DOF. If I'm fairly close I might go up to f8, or further away down to f4 or even lower if necessary or I want a small dof. As for the 1/160, again, for myself, it's sort of a default shutter speed I use with the flash, if I want more ambient light I'll go a little slower or open up to maybe f2.8 or f2 if necessary. Not too much slower on the shutter or I get the "shakes" involved. Again, that's just me, you're right, each situation needs customizing.
