If the after session chat's got any influence I'm yet to meet someone who owns either of these kites say their disappointed.
I bought a Dyno 17 about a month ago (current model LTD) .. have only had it out in Botany Bay, but #u$k .. awesome low end grunt, turn's are snappy for a 17 and it doesn't mind being out there in 8kts or 20kts - 5th line helps with a speedy re-launch too.
