Gees Sprucey, take a chill pill mate. It's hilarious that forum junkies take a swipe at schools and shops for creating uncontrollable crowds at their local, for increasing prices on new gear and now it seems for de-valueing second hand gear. LOL
Allow me to explain something to you. As a professional instructor you have a legal "duty of care" to your customers. That duty of care is to take all reasonable action to ensure the safety of the student whilst in your care. When a safer piece of equipment becomes available on the market, it is decidedly prudent to offer this equipment to the customer to further increase the level of safety, fun and to help maximize progression.
I also have a 9m Airush Reactor I cannot hardly give away, so I'm in the same boat. "C" kites are in the vast shrinking minority so we offer gear that suits the majority. I don't want to keep festy old 4 line kites around in my trailer for the 1 in 50 people who have old redundant gear.
If you re-read excerts from my post below, you will note we DO teach for FREE the differences on a customers kite after we have given them a lesson and they can fly the kite competently. It is OUR school policy not to use customers kites as we believe they are not as safe as the ones we supply, this just further reduces the risk of incident.

We generally get students up and riding on our gear and then show them the differences between the SLE and "C" kites. Primarily the differences are water relaunch, solo launch and self rescue. We usually teach these things for free once a student has done a lesson with us on our gear, so they can go ahead and practice on their own gear without killing themselves.
New gear is definately safer and the progreession is way faster on SLE. Older gear is fine too as we all rode it, gees I even learned and spent a season on 2 line kites in the beginning, but 4 lines were safer and now Bows are safer again. Personally I'll be glad to see the end of the no big depower "C" kites as they seem to be ending up in the hands of newbies with little money cause people are practically giving them away. But thats another thread.
But hey, thanks for your abuse and your obvious concern for justice

Good winds,
