Does any one know anything about the 03 frenzy, i.e what are the major differences in the new models

Each year of Frenzy has gone through some kind of modification or upgrades to improve the design and performance. The '03 Frenzy was a great kite, I liked it a little better than the '04 model because it seemed to be a little more stable. The '04 and '05 models were a bit more powerful and the bar was a bit cleaner, the '05 was a bit more stable than the '04. There seemed to be a pretty good change in the '06 models in stability and power. Plus the '06 model came with the Re-Ride system on it which is IMO one of the greatest improvements in the bar safety design.

I would seriously look at the cost of each. If there is a huge difference in price from the '03 to the new '07 and if the '03 was in awesome shape then it would be a great kite at a bargain price. If the price was not that much lower than the newer models or if the kite has been abused excessively with repairs or serious wear & tear then I would opt for the new model for the extra bucks. With proper care the Frenzy will last many years and when you figure out the amount of use you can get out of it over the years compared to the cost it is a great bargain.
