Is it really that much of a killer???
It's amazing how few people consider that sad reality.
My Metz 60 has a full power burn time of right around 1/200 second, and I do find when doing daylight fill, I am often using a lot of power, so it wouldn't surprise me at all if a 1/250 second sync speed is unrealistic without some of the more e$oteric flash equipment out there.
I believe this issue has come up on a Canon forum where a Canon was cutting off some of the flash exposure at full sync.
