For the intended application and at that price point, it may be suitable to go for a TI road frame and eno hub.

It seems that you're already dead-emeat-set on a SS carbon complete, but might as well go for dual purpose. Not completely sure what you're training for, but if it's crits, boom, you have a back up---your trainer---set up of course.

TI will treat you well, if not better than carbon and will certainly outlast it. There's just nothing really tempting to the Felt Footprint from this perspective. Could just as easily go custom steel frame, or second-hand TI complete.

And I'm just postulating that you have a fully stocked parts bin.
