I agree, but I have had a couple different arrow brands that spine did change in...Umm Eastons...for one(cough)
but spine consistancy will affect the flight of your arrows more than a few grains...was my main point.
My Goldtips are the best arrows I have found...I also have some XT hunters that have the original logo on them
I agree bro with your main point. Spine IMO is still the most overlooked thing in archery
