Trying to get some extra oomph out of my 60 CT-4 System. I see there are two connections for heads, but for a second head you must use a mecatwin (special head with capacitor inside) instead of another 60 CT4 head.

Anybodoy know if the older Metz 402 mecatwin head will work with my new 60 CT4 system? Do any versions of the mecatwin offer manual output or just manual at full power?

Finally, anybody know how powerful these mecatwins really are? Am I doubling the power of my 60 CT or just increasing it by a smaller ratio?
