Hey, if your Z-240’s or what ever you are shooting with are working fine, than there isn’t much to worry about.
But, if you are at a point where you need to get new strobes, there’s plenty to worry about. Like, which ones do I get and will they be the right ones?
Of course, once you have finely made your choice and placed your order, that worry is soon replaced with the new worry of will they get here in time for my net big trip or will they arrive too late?
And so it goes.
