I can certainly agree with this...
Although I am a fairly low airtime pilot, my instructor suggested that my flying way good enough to try the Sigma-3. I loved it... my main likes were:
1. Launches easily and smoothly.. both Alpine in light winds, and reverse in stronger winds.
2. Turns very accurately and is very responsive... (It does tend to bank up quite quickly if you bury the brakes tho!)
3. Pitch Stability is very good.
4. It's resistant to tucks, especially the sort you get during reverse launches if you don't hold the glider back enough.
