Hi, I'm doing a few evening events this summer so jumping between indoor light and summer evening light. I prefer to use fill in flash (SB800) and have achieved good results with the Gary Fong dome. However it's version one and the weight of it often causes it to come off or the top to fall off which is very frustrating. Before i upgrade to the latest concertina version i wondered if there were better alternatives out the that people have used ? Thanks in advance, Mike.
