Early Jabbys do need lots of hands and feet work and do "wag the tail" in turbulence - much nicer with a bigger/longer tail.
As for it being just for middle aged people who can't pass a medical types - get over your selves! Most Jabiru drivers I teach are either ex GA or have moved into GA. The medical issue is for the most part irrelevant (and if EvilUltralights wants to debate this please use facts only!).
Yeap the nose wheel will break if you try hard enough - I've never had one break and neither has a student of mine ever broken one. Again an issue but the more you know about the issue the less of an issue it becomes.
Gazelle is extremely easy to fly - unlike the Jabiru - which is a good and bad thing. This becomes like the old Holden vs Ford arguement.
Tecnams are great but VERY pricey. Plenty of better value out there and locally built.
Have a look at the Light Wing Speed - Just as nice as a tecnam but cheaper and more robust and LOCAL.
