Of these, I'd go with option 2. In practice, my bikes are either full-Rival or full-Red, but I were piecing something together now, I would consider a mix of the two. I have no use for force parts. The price/performance ratio isn't there for me. The only exception might be if I wanted a carbon crank but didn't want to pay for Red.

If long-term costs matter to you, look into the cost of Ultegra chainrings. They will run you more than other options, and the crank won't look right if you were to use an off-brand.
