I've watched all the videos for VF7 and I have very mixed thoughts about it.
Positive:
Lots of good fliers
Some neat tricks/combos
A lot of fliers entered
All videos on youtube = no quality bias
Negative:
Every routine is sloppy compared to normal ballet/tricks comp routines, some more so than others obviously
Everyone's routine looks rushed, no exception
--------
I really think that the 1 minute limit is far too short. I've watched the last 4 VF's and it's been VERY rare (2 videos) to see an entry that does not look rushed and full of tricks with sloppy entrances, exits and overall execution.
I am all for the idea of a full-out trick competition but based purely on observation it seems that there is a limit imposed on competitors that influences them to perform at a level much lower than they are capable. Simply comparing videos, or performances seen in person by many fliers to their VF entries is evidence enough. I know of many entrants who can fly for a good period of time without any "mistakes", showing some level of control, but their VF entries show quite the opposite.
Another aspect is that a 1 minute time limit also removes the ability for it to be true freestyle (doing what you want/love to do). If someone wanted to fly a basic precision figure they would likely not even have time for even a couple of tricks. Likewise there are flying styles that are put at a large disadvantage by the time limit simply due to the style of tricks which require more time to execute than others.
I really think that for vf8 the limit should be more flexible. 1-3 minutes seems more than enough.
I do not see any reason for keeping the videos at 1 minute anymore (previously I could understand bandwidth issues). At this time it puts many fliers at a disadvantage for absolutely no return at all.
