westozkiteboarding.com.au/ Have you talked to Jason? he is the blade retailer around here. From what I hear and see, they seem to be good kites, and if you go to safety bay or just in front on penguin island when it's windy there is a very good chance you'll see some blades there, as a few people ride them, so you'll be able to get some infos
Sorry i can't help you more on this one but talk to Jason and the blade riders on the beach and you should get all the info you need for those kites
Cheers
