Yeah, Olympus groupset was a bit of a curates egg with the front mech not one of the best parts. At least you haven’t got the terrible Olympus brake levers!
Personally I think your Record OR levers are some of the nicest ever made, they’re so elegant. I never got on with Bullets at all though. Despite the best efforts of several mechanics, we couldn’t get them to work adequately. Sometimes they needed two hands to shift! Raleigh ended up replacing them with Record OR/Icarus thumbies. That’s what I’d look for if you want Campag.
