The Cactus brand triggers have certain models that are rated to withstand high synch trigger voltages, so in that way they are different from most of the cheap triggers out there.

And with the exception of the original RB67 Pro models, the RB67 has most of the same safety interlocks as the RZ67 models.

The RB67 offers a 6x8 option, whereas the RZ67 does not. It is a bit difficult to put into effect, as the necessary accessory parts are not well documented.
