There was a good discussion about Bell Vs Agusta in this thread
http://www.pprune.org/rotorheads/308...-costs-uk.html
Some of the guys there did seem to know a lot more than me about the issues, although there was never a conclusion.
Let me know if you need any more help or contacts at Agusta. I can supply you with a copy of the letter I had from Agusta if I can find it in my files.
