I think I watched the part with the model and the snake about... oh... 40 times. Stunning, stunning girl. Every time I watch a Joe McNally video, I buy another 580EXII and another FlexTT5. Your really can't have enough of them.
phottix odin is much better then the PW flex system.
PW has issues with the flex system.
the phottix system has an LCD and is cheaper and works perfect with canon flashes.
i had the old PW for years but then i tried the flex system and was dissapointed.
the phottix odin system in contrast works 100% flawless with canon flash units.
