F2c is an 06 with DA except SLK crank and SSC SL


F15 is 05 FULL DA with SSC SL

Both are in my fit range and both are around $2500 with very light use. I am looking to get a race day/climbing day bike that is stiff and light around this price point. I have found others, but these seem to be the best deals... I'm open to other sugestions as well...

Thanks!
