Wonnakite - the 07 Waroo is a great kite for a beginner - I bought a 13 second hand on SB and had my first ride on it today. Im 83 kg and flown a few kites before. The Waroo is stable, doesnt flutter or flap, had me going up wind in 13-15kn on a 133 twinnie. I guess the 13 is a bit slow on the turns, but it is a big (and poweful) kite.
One thing I would mention is that the relaunch is a bit harder than say a true bow kite or a rev. I had a bit of trouble today but the wind had droped to 11-12 kn and I think thats what made it hard.
Stable, very smooth, lots of power easy self launch and land, and best of all - (no pun intended )an absolute bargain at $500! - I am absolutely STOKED with this kite and was hooting and punching the air today.
The only negative is the quick release - the design is sh1t impossible to reset in the water getting pulled - and it doesnt flag out - check out the rev
other than that cant go wrong

PS. I couldnt find much in the 'search' as I think the 07 waroo came out at the end of 06 and the posts dont go back that far.
