I’ve used both. Zees haven’t failed me yet but the XTRs are definitely much stouter. Agree with you on the height of the XTR Signatures. Wish they could make them in a low. I’ve actually had no complaints with the SWFA rings. Not as refined as some but seem to align well and hold just fine.

John

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land. 2 Chronicles 7:14
