Better to get a piece of clear tubing with an ID of about 1-1.5mm and about an inch shorter than the gap between the two housing stops. That will actually protect you paint and stay there. Best is for builders to put the housing stops under the top tube...

That was my experience.
No, the best thing is for frame builders to copy what Calfee did on my Luna: Instead of a cable *stop*, it has cable *holders* on the tube tube, through which the housing passes. i.e. the housing is one continuous piece from the brifter to the rear brake. I had never seen this before, and was skeptical that it might result in a mushy lever, but that fear was unfounded.

I didn't think anybody, except vintage style steel builders, did that any more because it adds weight, can reduce breaking performance, and is completely unnecessary.

So that makes the frame stronger or weaker? How?

I removed all the donuts, cleaned the cable with water and alcohol, and then I molded blobs of ShoeGoo onto the cables. So far, they haven't moved since they are bonded in place. They're not as quiet or discrete though.
