Another option which I use is a gear head. I use a Manfrotto 410 with my Sinar Alpina and also with my smaller cameras. I like the gear head because it allows me to level my camera quickly and very accurately. This may or may not be important to you depending on your subject matter and the look you are trying to achieve. I answer to your question yes you call use a ball head for large format and since you already have one that I would recommend that you start out with it. You call away buy a different type of head if you don't like the ball head.
