Cannondal R2000 or Felt F65...

Hey, ive been in the market for a road bike for a while, and ive done rediculous amounts of research, out of everyone on the planet that dosent own a road bike, i probably know the most about them. Ive been looking for a 1500$ bike and called up a LBS a few days ago asking about a Felt F65, seemed like an awesome bike, full ultegra (*and came in 63 for me). As soon as i told him my size he said someone mis-ordered a canndondale six13 2000- and he could get it for me for 2250, 750 off MSRP cause they would have wasted so much money sending it back
now the F65 fits my budget to a T at 1425$... but this six13... its a six13, with centaur components (ive been a big fan of campy since my dad got his bike 4 years ago) and its 750 less than it should be
what do you guys think i should do... oh, and im only 20, this will be the single biggest purchase of my entire life regardless what bike i choose
let me know what the more experienced riders think- thanks alot
