I have a hotshoe to PC on the camera. I got a PC triple splitter type of thing so I can run two 45's with cables. Well...IT DOSEN'T WORK! They fire but it is soooo inconsistent. They don't know what they are doing. One is going off while the other dosen't both go off at full power etc. I tried every setting on the heads. Could not control the light. 45 ct5 and 45 cl4. Anyone do this with cables? What you are firing them with? I initially had auto but realised it was messing things up so I changed both to manual thinking my problems were over. No. Same thing. Both firing then next shot one firing then next shot other one firing alone. all over the place. I wasted 3 hours trying to figure something out. I ditched the whole shoot as it went dark outside! Also, the ct5 just kept firing on full power no matter what I set it at even though a test pop from it's own button was creating the reduced power pops. Gawd it was confusing. Also, if you bought a cheapie remote trigger from ebay, could you show me (ad urls) which one worked with your metz 45 and have you used it to reliably fire two simultaneously? I think metz can give you a headache.
