Mr. Habitus - Yes I am taking this mighty steed on the ride tomorrow. I have moustache bars on it so it can hold lots of balloons!!
Mr. Dave - I do pretty much the same as you, but it's not upside down and I probably should adopt that. I also find that it holds well if I just adjust the hub with my fingers. It's so stinkin' easy there's not much technique needed. If only everything could be this easy......well hell then everyone would do it.
