Just re-read your initial post... similar situation here being offered a pair of the 84 EDTs for a pretty insane price (under $600, they were skied on once... well, twice, the 2nd time by me). I almost pulled the trigger but ultimately I want a shorter turning radius. I still want that ski though, It was so much fun. If I had enough money to have more than one pair of skis it would have been a no-brainer. I was hoping the 76ti would have the same kind of excitement with a shorter turning radius but I personally didn't get that. Compared to the 84 EDT I found it to be squirrely, not very stable with even a moderate amount of speed, and the edge grip wasn't anything to write home about. After just a few runs I left and drove back to the demo shop to get a different ski. Compared to the FA 84 EDT the 76ti felt like it was in a different (lower) class of performance (opinion of course).
Enjoy your new FAs!
