The OEM 6m extensions are important, so you get a proper long power stroke and enough time to turn the kite - it's a looooooooooooong kite up there!
Don't forget the Speed series also has Triple Depower - you sheet out, you reduce the angle of attack AND the amount of projected area AND alter the camber of the kite. On the beach, sheet in and trim the kite until it doesn't back-stall. (If you have to do that at all with the 21, your lines are out of tune.) Now you're good to go - you'll have pretty much full power with the bar a most of the way to the QR. Speeds like a light touch on the bar - no big movements, keep them steady and smooth.
Tip tucking - if you sheet out and turn, that'll happen. See above re. Triple Depower. Gentle sines, long strokes, park as soon as you can and build board and kite speed.
For me, in light wind, a down stroke, then up and park is enough to get me cruising.
