Hughes500,
I think I can answer you question but before I do, I want to make one thing clear. 206 Jetties are
great machines, but they are a 40 year old design and (this is important) they don't make them anymore.
The weight difference is due to the fact the the 66 is a smaller machine in terms of body length (it is the same width) and the rest of it is Frank saving weight to add to performance. Does that make it less "solid", probably, but what does that mean in the real world ? Maybe not a lot.
If I had $2.2 meg spare, I would probably get a L4, which has HEAPS of power and is a proven performer (and yes, you can still buy one new). But I can get 2.5 x R66 for the price of a L4, and I can talk to the PAX face to face.
As I have said prior, I haven't made a choice, and I thank everyone so far for their constructive comments.
