I don't belong to a club, as unfortunatley there aren't any near me. However I do think it sounds like great fun, not just for Ollie and Chachi, but also for yourself.
I would go and try it out, and see what you think, i wouldn't worry too much about clicks, as i find at most group activities nowadays, people are always in clicks worse luck
I think the benefits would mainly be socialising your babies and having them acheive something, you might also make some good friends along the way, and enhance your knowledge on dogs in general good luck
