Canon S5 IS + Bowens Gemini strobe synching problems

Hugowolf, thank you much for the response.  Yes, I have read many blogs and forums stating that the sync cords are not reliable, that is why we tried using the radio trigger.  The radio trigger produces a worse misfire rate, however.  I have not thought about trying a Nikon hot shoe to PC sync adapter.  I purchased the Weinsafe out of desparation, thinking something about it might provide more reliability, especially at $50 a pop.  It does seem to provide a very snug, tight connection to the hot shoe, but beyond that, I don't know what benefit it confers.  Thank you so much.
