Generic settings?

[kafene]

I'm going to shoot a friends wedding (luckily, i'm not the actual paid photography, so no stress).

I'm using a flash that doesn't have TTL (my new Canon 10D doesn't work with my previous flash units). I used to shoot with a "generic" setting like 60 / 5.6 and adjust the flash power as needed because I can get to shooting a lof of pictures in a short period of time and don't want to meter every shot.

Does anyone else shoot with a set setting similar to this or should I try someting different?
