Im not sure what everyone else thinks, but I have found along with some of my key riders in mackay that it is easier to progress into freestyle / wakestyle moves using a larger kite. We have sold plenty to happy customers.
Reasons:
- Kite is less reactive, making it easier to place the kite at 45 and be assured it wont drift much.
- There is a definate lull period at the apex of a move, making it ideal for first attempts at handle pass moves (back mobes, slims) etc. Basically once you load and pop, your body catches upto the kite and the bar becomes slack for a second or 2. This is alot harder to find in smaller kites in stronger conditions, unless you ride the new BEST 2008 YARGA, released next month...

The main drama with big kites, is relaunching is generally a little harder, kitelooping is almost out of the question, takes longer to pump up, kites become more expensive the bigger they are (unless you get closeout sales).
For the heavy people I think they are great. Just whatch what bigkites you choose, there are some real pigs out there that I have flown, and then there is the good ones like the waroo pro 17. Great kite and has all the performance needed.
I am happy to help with any questions. Ive been kiteboarding on big kites for over 8 years and see the light
