"Best for pilots with competition and high-performance glider experience. Located in Colorado." Do you consider that the JS3 is particularly demanding to fly by comparison with other flapped 18m gliders?

As a JS-3 owner and middle-of-the-pack contest pilot, I find the JS-3 a delight to fly and have (after intentional provocation) not uncoverd any bad or surprising behaviors whether 15M, 18M, empty or fully ballasted. All 18M racing ships are slippery, so a direct transition from say a 2-33 would likely be a bigger than desired step.

what do you mean by slippery?

Slippery means exceptionally low aerodynamic drag. In the case of the JS3 it has very low drag across a wide speed range as well as a small wing area and resulting high maximum wing loading. This enables it to have a very high L/D at high cruise speeds. It also means that if you point the nose at the ground with the spoilers retracted and the flaps negative it will pick up speed in a hurry. So, if you let yourself get into a nose-down attitude you will potentially get to Vne surprisingly quickly if you are not used to it.

After two contest seasons with my JS3 I have not found any bad habits either, but compared to my ASW-27B it will get to 100, and then 130 knots very quickly with very little change in attitude when you transition from climb to cruise. It's actually quite satisfying - I don't think any glider short of the Concordia runs at high speed like a loaded JS3 with the 18M tips. I've never flown a glider that wanted to cruise at 120-130 knots. But what comes with that is that one is well advised pay attention the the airspeed indicator.

That's why you have the LXNAV lady warning, "OVERSPEED, OVERSPEED!"
