Hey,WorldIRC --- you didn't make it multiple choice! What you think we have the same type of shifters on ALL of our bikes???
I voted for Ergo levers. That's what I have on my main ride. However, I also have bar-end shifters on my 'cross bike (friction) and my tandem (indexed). When I rebuild the old Italian road bike (Romani) I'm putting the 1980's vintage Campy Nuovo Record downtube shifters back on.
Ciao, Steve
