When I bought my ACC's 3 years ago,I was puttingup to1000 arrows a week through a bow.Atleast one of them.
These arrows have been shot a lot.Just for some reference.
My biggest reasonfor not choosing goldtips was because they really didn't have anything that spined RIGHTfor my lower energy setups.They may have now,but I quit looking at them when they moved.I do like the pin nock system.BUT,I am having NO problems with the g-nock,uni bushing system.
I would be willing to bet that there are a few world records that have been shot with the old,outdated ACC technology.
Check your arrows only if YOU want,I would be interested as would othersbut you need to prove nothing to me.
I just saw something,the Gold tip Pro 22's are +- 1 grain,the ACC's are +- .5 grains.The ACC's have tighter tolerances.

SEE HOW SILLY IT IS.
