Congratulations!! Welcome BACK to the Trek 720 club!!!
I think that bike looks plenty pretty.
I'm confused- those look like DiaCompe brakes.
The Cyclone stuff shifts so nicely- and that FD- it's crazy how lightweight it is, it's a beautiful, graceful, ornate piece, it's exactly the same as would be on a "racing" bike of the time- but it works GREAT on triples- and not just triples- but going from like a 45 to 28, and it's a champ. It came with an extension that ostensibly lengthens the cage and lowers the bottom of the cage- but it totally works perfect without it. I haven't used an extension- but I've read they only cause problems- the chain is more likely to get hung up in the extension and screw than it is ride on the tail of the cage.
The Phil hubs are something else way cool. I've had sealed bearing hubs, but the Phils I have on my 720 are outrageously smooth. Love 'em.
Trek Decals... Everyone has their own favorite- My personal favorite is the 86-87 DT decals, followed by the 85, followed by the 81-83 seatwrap (like this one), and the 84 decals are tied with the original 77-81 letters on a tube decals.
