MGOOF : Modern groupset on old frame

The Campagnolo Ergopower hood shape felt much more natural to wrap my hand round them, the latest one with the smaller downshift button were extremely comfortable;

For some reason I found the 105 5800 (et all) hood surprisingly uncomfortable except for the Di2 one.

The older shape were comfortable enough (especially as a singlespeed levers) but the downshift button although great to shift a whole gear in one stroke, felt like it's on the way, and the gear cable routing made the transition from hood to bar a bit awkward;
