Danno83, welcome to the real side of the dark side! No worries, glad you relize that revs are the real deal.
The vented revs do fly in higher winds and the less venting is lesser wind capability. Now that doesn't necessarily mean it will float, it takes practice and patience. Really, I have never flown, touch, or even see a "Revolution" knockoff, but I imagine Revolution Kites are angels compared to those. Revolution is the only thing I have flown, and I own three of them and four frames. I love them, and want more. The frames are very important as well as the sails and venting. The best and lightest frame is the diamond frame, but I don't advise getting this first just because it's very fragile, except if you live in a region where you have 0-3 mph wind.
I recommend the race frame or green race frame for light wind 3-9 mph and the 3 wrap frame for everything else for higher wind 8-14 mph. The race frame has loads of flex and the flex really compliments the flying characteristics in my opinion. The three wrap is the "standard" frame. There is a 4 wrap frame, but it so stiff I find it uncomfortable to fly with, although I do fly with it in very high wind conditions. Personally for sails, if you have average wind get the standard b series with a 3 wrap and a race or green race. (The green race is nearly invincible, the race is lighter). Also, get laser pro gold and handles. Get everything new, just so it is all revolution quality standards and so the knockoff strings dont hold back the legit kite.
Take my advice with a grain of salt and I'm sure some other people are reading this and disagreeing with some things, but this advice is my opinion. Hope to see pictures of your kite(s) when you get it!
