YES I do, but I'm in a special situation where I have to always have the latest. In saying that though my small kite (7M reo) is a 2015, because the 2015 and 2016 were the same and I never lend that size out for demo anyway.
But this also means some lucky (generally local) kiters get to buy my not heavily used, always unrepaired, last years kites. I'll be selling 12/10/9/8 2016 Reo and that 2017 7m reo in approx 1-2 weeks when I get my hands on the new V4's.
Some people seem to place a lot of value on their used kites. By that I mean they actually purchase a brand based on how well they think this brand will hold its value, these people tend to trade up to brand new gear every 1-2 years, because thats when they get the best price.
Others find a model they like and just ride them to death. If I did not have my job, I'd fall into that category. Some of my early 2 line power kites and trick kites are now more than 20 years old, guess what? They still fly the same and give me the same fun! I've even got a line set that I use on a favourite power kite set up, its 2 line x 300lb spectra and its at least 20 years old and still going strong as of a few weeks ago. Kite stuff does last quite well if you look after it, but of course if you don't or accidentally get your kite munched in waves or eaten by sharp rocks, then its often game over for that one.
