especially in low wind, you'll need more training ....
i figured out that it's more effective to ride in a 'staircase ..' you go upwind till you feel that (because of the edging) your kite gets bad-tempered. rigt before you drop out of gliding, fly the kite up and drop to halfwind - riding. gather speed by dropping the kite and when you go fast enough start enging harder and go upwind.
this worked well with flysurfer kites
(don't fly them full powered all the time - if you depower, they fly faster)
arc's and arc - stacks.
(i dont like big tubekites that much)
