The Verso and Grafit can definitely be integrated together flawlessly. The Verso, although a new design, will take any head manufactured after 1973. So it is fully compatible with the full line of Broncolor heads and accessories.
Someone has mentioned the Mobil pack in another message. This is a good less expensive battery option but is not fully integrated. It will take the range of heads but offers no modeling light or fan. The Mobillite is the only head that offers modeling light on a mobil pack.
The Grafit does not offer a battery option. Your choices for powering on location would be limited to a gas generator and it must be a voltage controlled one at that. If you are in the studio the Grafit gives you the most control and larger list of features. It's recycle time is a bit slow if you are shooting fashion though. That has to do with the number of capacitors and the circuitry that give it 3 independently controlled channels.
The Verso is 2 independent channels with 3 sockets. Much faster recycling time of .9 on AC and 1.5 sec on Battery, but does not offer the features on the Grafit of controllable flash duration, delay, programmed multi pop ...etc.
I guess it all depends what type of work you do and and your needs. Fashion I would lean towards the Versos, while if you were a table top shooter I would definitely go Grafit.

i have an all broncolor system. with regards to mobil pack, i have both the mobilite and picolite flash heads. mobilite is use when you're on battery pack. but when i need additional pack for studio work, i attached the ac power adaptor and use the picolite head which have a modeling lamp. the mobil just becomes a regular studio power pack wherein you can use the modeling lamp of picolite. hope this helps.
