I was just thinking about Modolo Kronos levers this morning, I have a pair, also rotted hoods, but also have a NOS set of hoods in the original packaging, got them with a bike I bought a few years back.

A bit of a head scratcher at first to divine how they clamp to the bars. More comfortable than their non aero contemporaries, but a bit mushy in feel to me. I did not try to set them up loose. I too would only use them with drilled bars, radius the holes to help control stress risers, and Cinelli bars are favored by me over the single thickness type, at least some of the holes can be placed at a double thickness region.
