Aerbabe - all my early light aircraft flying was done in the back of a Chippie as an air cadet - great fun!
First 3 hrs of my PPL were in a Chippie (BDIC at ANT, Blackpool) - probably about 2.5 hrs of those were spent attempting to taxi it!! Mind you, I was a youthful 18 year old then and not aging / grey as I am now....!!
I vote for the Chippie, but have never experienced an Auster / Cub / Citabria / Moth, so maybe should keep my mouth shut due to lack of experience. A major part of my vote comes from the Gypsy Major experience - an absolute classic sound (so that covers Auster and Moth as well!).
