I will be using them on a K20D & with a Metz 48 flash. Have you tried holding in the button on the transmitter while you are taking the shot, that seems to fix some of the problems with the shutter curtain shadow at 1/160 & 1/180 so may also help with the misfires but I'm not sure so it may be worth a try. Hopefully the Canon version don't do it.
