I trained on the robbie but have a little time in the 300,and as mentioned it is a very manouverable aircraft and I found that the 300 was really quite slow given a hot day, and the "throttle work" was limited because we were on full throttle the whole time and regulating the RRPM with collective/air speed so the "no govenor" issue didn't really make much difference. I was told (and 1 agree)that transition to the 206 was easier if you were used to the R22 and as that was where I was heading, it made sense. As for the T bar. I once asked this pro with WAY more hours than me what he thought of the T bar after his first robbie flight. he said "didn't really notice till you said"
