Hey Craig. Yeah, freshwater lake up here in Canada. Wind that day was blowing around 50-55 km/h and was pretty gusty. The 10m Diablo is a wicked kite. Has all the same characteristics of the bigger Diablos but just responds alot faster. I have had it out in up to 60 km/h winds but that is about the limit for it for me. Anything higher than that and I switch to a 6m Diablo just because when the wind gets that big around here it gets really gusty and it’s better to be a bit underpowered sometimes and not have to worry about getting slammed with a huge gust on too large a kite. You want to have some fun you should try out a 6m Diablo, that thing is crazy. You can dive it and when it is 2 feet off the water just pull and it shoots back up without hitting the water. Retarded fast.
