How do you fit two flashes in the Lastolite 24" I have one and don't see how two would fit, I'd love to get two in there though. I hate the stupid plastic lollipop thing, and the coldshoe is crap, I replaced my coldshoe with a much better one but haven't found a way around the damn lollipop.
I rubberband the heads together and slip em in, one in cold shoe (I use an RSS) one on top. I use heavy duty industrial bands with a thin piece of rubber in between so they do not slip. The "lollipop" (laughed my ass off) I modified by cutting out the "window" in the middle into a full circle using a small Dremel tool and some sand paper to smooth the finish. Fits two heads just fine (may be a bit tight with diffusers). When I get home from my trip ill post a few pics of the mod. Took me about an hour.
Here they are with my rouge gel rubberbands (which I WOULD NOT USE. Get nice thick heavy industrial ones), only thing I had, before I toss them into the cold shoe. I am working on bending an aluminum piece to hold the top flash in an RSS cold shoe upside down so I don't risk my 600's.
