OK. I'm not qualified to critique your vid. Neither is Leif but I wouldn't say that publicly about him.
Anyway, the reason I'm posting in this thread is cuz I think flat water tricks in a volume boat are way over rated and tend to create bad technique and even "bad" boaters. It teaches a poor relationship with the water. Flatwater freestyle tends to create boaters who try to use power to do tricks that are meant to be done fluidly with a rio feature. The best play boaters are flowing with the rio and not trying to overpower it. IMO, the best way to develop in flat water is to get in a squirt boat. That will teach you more about body/boat/paddle positioning than a surface boat and it will teach you way more about working with the water than a surface boat can, even if you have a good teacher like Leif (please don't tell him I said that). I know most reading this either don't have access to a squirt or won't be able to hear it but I offer this opinion thinking it might make a difference for some. Its too late for Leif but he could never find a squirt boat cut for him anyway...
