I have a couple of Flashpoint xplor 600 strobes that I love using on location. My current stands have a standard round post that the light fits nicely on. I'm afraid to tighten it down too much for fear of stripping the fastener but when the wind is a little stronger my assistant has a hard time keeping the modifier and light swiveling on the post. Are there any replacement posts that I can put in my stands? I've try searching but don't really know the keywords to use.
