I see occasional questions here about 7/8 sized and similar small cellos. If you're curious what the tradeoffs are, here's one of Masumi Rostad's ongoing series of interviews in which his guest addresses the subject from first-hand experience as a professional cellist.

This is one episode in an ongoing series about how string players relate to their instruments. The interviewer, Masumi Rostad is an in-demand violist whom I met some years ago when I was recording a chamber music festival where he was featured.
