What magic do the JS3 and Ventus 3 have that the ASG-29 Does not?

Come on, guys! Help me out here.
I'm trying to negotiate a fire-sale price for '29's.

3 year wait for a V3, btw.

Yep Bojack, think of all the problems with the 29, Flutter, wings falling off, complete melting of the fuselage in the hot sun. The list goes on and on, maybe we could get two for the price of one.

Three year wait for a V3 or JS3 plus they will cost every bit of a quarter million dollars. In 1994 I purchased an ASW-24 with two hours flight time on it for $40,000.

Unless you want to fly on the money bleeding edge in comps, last generation gliders become bargains, with 99% of the performance.
As an example, when I last visited my glider repairer, he had a JS1 he was fitting new winglets to.
The performance gain was .25 of an L/D point at 100kt, at a cost of $7000 aust. Must be the most expensive LD per dollar ever.
Given that manufacturers give gliders to comp pilots for WC as a marketing tool, as shown by Schemp lending Adam Woolley a V3 for the recent Hosin comp.
29s and 27s V2s will be good value buying the near future.
Or you could give up gliding, buy a Stemme and fly a light plane. (:

As usual, you're just blowing smoke, dreaming up numbers off the top of what is left of your head.

Not true.

Irrelevant - no one adds winglets to gain L/D at 100 knots; generally, it's to
improve the low speed handling, thermalling, and low speed L/D.

Did it ever occur to you that different winglets might have less drag at 100kt?
Perhaps try thinking before stating the bleeding obvious.
Let’s make it simple for you, old winglets work equally well at low speed, more drag at high speed.

I'm no expert on winglets, but it's my understanding that not all old winglets work equally well at low reynolds numbers. I've heard some factory winglets were quite ineffective so the owners went to 3rd parties. Someone help me out here; I believe I read that some winglets significantly improved the safety of certain models (Ventus? ASW20?) from low speed wing drops. Not a physicist, yet I highly doubt you can accurately measure a 0.25 L/D improvement at high speeds. What method did he use to test? That seems to be well within the noise. (BTW you got docked points for rudeness. It doesn't encourage free exchange of ideas. I'm sure you meant well.)

Quarter million dollars.....yikes!!!
