Appreciate this so far...It sounds like we should pay attention to specs/matching, yet it’s likely not bible. I’ve enjoyed Koetsu’s (Rosewood standard and Rosewood Sig) on a Graham 2.2. This is going back too far to help myself here, but I believe others have had success using medium mass (<25 Gram) arms. However, I’m sure choosing a lighter arm increases the chance of running in to a mismatch. Perhaps there are still a number of good med mass choices, such as a well made gimbal arm. I’m going by what I’ve heard in my last sentence, but sometimes we have to operate without an abundance of info. Let’s face it, interest isn’t at an all time high in this hobby.
