Hmmm...I shoot lots of weddings each year, along with lots of paid portraits and family groupings - almost always flash fill. The 1/250 would be nicer, but the 1/180 is not a deal breaker for me. I generally set the flash to handle high speed and then watch my shutter speed - using ISO somewhat to help control things. Not a huge issue, just a small nice to have, in my book.
