I own both Guerlain Vetiver in the ribbed (original formulation) bottle and Vetiver Frozen and I enjoy both very much. Lately I have been thinking about getting a bottle of the latest version. While searching I came across this site.

What are the differences between the 1.7 and 3.4oz bottles?
Is the 1.7oz the first formulation of the EDT version of GV?
Should I bother with either one? Are they different enough from the two I already own?
These are the only versions of GV I have smelled.

Any comments and opinions will be very much appreciated.
