That's an interesting question.
I bought my 2008 9m Waroo off of Singlemalt.
The other kite I was looking at was the 8.5m Ion2. I flew the Ion2, it is great.
The new 9m 'roo is great too. So both kites rock.
If it were me, I would pick the one you feel will be best warrantied and has best resale value for you. The kites tied in my mind in terms of performance, for my particular style of riding. My decision came down to warranty and resale. Odds of needing a warranty on a Flexi are low. Therefore resale was the issue.
I was going to pay a higher price for the Flexi in my situation, it's resale locally isn't that great relative to the new price I was going to pay. The waroo is the opposite, in my location.
Go with what feels right, you won't lose either way, imo.
Best has a bar.
I guess the 2008 bar isn't out, but the 2007 works fine.
I actually use that bar on all my kites, Best or not.
