With a few hundred hours in the L series and just a few hours in the 407, I can say from the aspect of tourists and Charters that the difference is Day and Night.
Now that Bell has most of the bugs out of the 407 I think its going to be a fine Aircraft in the single category.
Its faster, hauls more without loss of power and is a bit more comfortable with the four bladed system. (providing all are tracked)
In comparing prices for a new L4 and a 407 based on the reults in time saved on Charters. I think more folks will opt for the 407......
My 2 cents
