Felt F80 or Felt F75

[GumballStyle]

Still looking into which bike to get. I've called around most of New England and checking with various bike stores. I've found a Felt F80 with full 105 parts all around, 3 wheel crank set, and Alex wheels for $750. Also found a F75(a small step up) for $900 with 105 and Ultegra parts, 2 wheel crank set, and Shimano WH-R500 Aluminum wheels. I also found a Giant OCR Composite 3 for $800 w/ 105's. I could go any which way. I don't think the Giant is for me as I'm looking into serious riding and several triathlons. Any thoughts as to what you think would be the best? Should I go for the F75? Specs are below.

Of the Felts, def the F75 for that price. I have the F75 for the more retail price of 1300 and find it very worth it. I don't know anything about the Giant. I personally see no need for a 3 ring crank, so that is no plus. On bikesportmichigan.com there is a pretty extensive write up on the F75.
