Berg Cup (German or Swiss hill climb championships)

[screwloose]

Already tried asking in general motorsport but to no avail so might as well try in here...
Having seen various videos and clips of this hill-climb championship and the awesome cars I'd like to go to one of the events this year.
Has anyone been?
Can anyone offer any inside info/tips etc?.
Which is the best one to go for?
Is the Swiss hill climb (bergrennen) championship different from the Berg cup?
Which of the championships offers the best cars?

thanks in advance.
