I just got a 7.6fx last month, and I rode the 7.5, 7.6, and 7.7 before making the decision. Honestly I'm skewed toward wanting the best when I make a big purchase so I have no regrets later, but I just couldn't feel enough of a difference with the 7.7 to justify the price, and the 7.5 was not in stock in my size, so I got the 7.6 and figured I could upgrade any components I needed to later if I found any shortcomings. I've got a couple hundred miles on it now, and overall I'm very happy with it, but I can see myself upgrading the front derailuer at some point, and I already upgraded the pedals and saddle. I do wish I had disc brakes for some reason, even though I don't need the braking power, I just don't like the finicky nature of the rim brakes.
