Late 1980's Campy componets were bad. The first index shifting groups were the low watermark of the brand. I have a 1989 Paramount that was originally built up with Campagnolo Athena, allegedly the first Campy group to get index shifting right. It was terrible. IMHO, step back just slightly in time and put on NR, or put on a modern group, but skip the late 80's Campy index shifting.
