Anyway…back at the ranch…

I ran across a set of KZG heads that are ~20g lighter throughout the set. For juniors, or petite ladies, I assume, so I thought I’d build a ladies set. The ladies irons I’ve  built in the past are C2-C3ish, but these with a 35g grip, are gonna be in the B6 range, lighter than anything I’ve ever seen. I swing weighted an old US Kids PW I had, and it felt fine, at B2.5. So, my question is…is B6 gonna be an acceptable swing weight, and are there any concerns, anyone can share?
