I don't know about that dead end street, I have my own to worry about but... I have never liked hex cores because I feel the termination is poor at best and could be digging slots in agraffes that may be regretted later. I would use a mix of metric and American cores or wires to solve small problems of a big piano but on little pianos small inconsistancies will not likely be heard because of other deficiencies of the piano. I just don't like them new fangled thangs. And I detest "universals" because they never sound right. Never! Just my opinion you know. Newton
