Hi KS,
R22's remind me a little, of the Great Muhamed Ali ( or Cassius Clay if your old enough) when he said, " Float like a butterfly, and Sting like a BEE", well that sums up the R22 for moi! although it will not help you to choose, I learnt on the R22 and apart from a few hairy moments, I would agree with the poster who said " If you can fly a 22 you can fly anything" the transition from "T" bar, to floor mounted cyclic took about 10 mins to get used to, good luck to you, whatever you choose. However remember " The Butterfly".
