Helihub,
I think you have answered your own question.
For reference, I have flown both, and I much prefer to fly the 66, so much more power and no TR authority problems.
That said, the 120B is a lovely machine, really well made, but heavy (all that lovely stuff weighs a bit !).
I suggest you have a look at a recent thread (2-3 weeks ago ?) where a lot of sensible comments were made regarding these two machines (and a couple of others not in production).
In that thread I said that I have a mate who has a 66, and he loves it. More each day. Endurance is showing as far better than published, as is cruise speed (130 knots). I want a 66. Just need to find a "lazy" one meg to get one !
Cheers,
Arrrj
