Perhaps I'm not the best person to trust for an objective review of this kite, but having flown my new one on Saturday at Newbury I have to say how pleased and impressed I am with the Vented Akuji. It may not have looked terribly impressive during the competition itself, but by the time I packed up I was really happy with it.
It wasn't blowing a complete hoolie (Tony S will have to confirm the average windspeed) but it was uncomfortable flying a standard, so I set up the vented with the patches over the lower vents and it had a very pleasant feel even in the middle of the window. There was no wingtip judder and it was still fairly easy to stall (having failed a couple of attempts at a snap-lazy I did a direct upwards-flight two-handed turtle to complete the lazy susan right in the middle of the window, about halfway up.)
This is the best vented kite I've flown. For that all-important 'matching the standard (or comp in this case)' feel it beats something like the Nirvana HW hands down. With the weight in place it still does the nose-out trick set-ups like pancake and turtle which I've always had problems with with vented kites, and will roll-up as nicely as the comp, single or double-pop.
JR had a go too, so hopefully he might offer a little unbiased opinion?
