Thanks steve.. Just have 1 YN560's hotshoe separated from the body ..
Is that true that SB is extremely durable to drop, moisture, rain, burnt and long life?

Anything can break due to the dumbest cause... The SB's are good, but I would not say it is "extremely durable". It may survive a surprisingly hard fall, or it may break for seemingly little cause. But I personally have had no issues with any of mine; they don't get a lot of use.

Two shoot through umbrellas can give you a surprising amount of light. Your obvious problem with shooting groups that big is light falloff on the edges of the group. You'd want to separate the umbrellas as far as possible and position them towards the far end on each side of the camera. Then, work your way in until you start to lose light on the outside. If you're not able to get everyone lit, then try keeping our umbrellas out to the ends, and bounce an on camera flash upwards to try and fill in the middle.
