Can a proshop test the spline? I want to get them refletched anyway. Going to try switching to blazers and see how that goes. I have no idea how many shots are on these arrows. I've done all gun hunting for the last 4 or 5 years except for one 2 day hog hunt witha bow. Looking forward to getting back into bow hunting.

This is something that I have wondered myself as well. The arrows I have put 10,000+ shots on were a set of pro 22's that were waaaay overspined for that setup but flew like darts anyhow. Almost all my arrows these days are way too stiff for the charts except for my hunting arrows and my fita/field arrows.

is that (spine tester) what it's called? can't seem to find one on line to buy. would appreciate any info on that tool.

You could probably buy one, but it would be very expensive. I made mine as have others on this forum. Do a search on this forum and on google and you should find some examples to follow.

Our is home made as well. I will see if I can find a write up on how to make one and use one.

I have never used one, but did some pricing a while back.. Maybe a couple years ago. The ones (s) I saw cost several hundred dollars. I just can't see the justification if you can build one easily enough.

I imagine I could put a longer base on my arrow straightener and use that. Sounds like an interesting project.

ty guys. googled "spine tester" and found what i needed.

They were Gold Tip Expeditions and I have no idea how many shots but I culled half of the two dozen I was shooting. They were visibly running out about 1 to 2mm on "The Arrow Inspector". Kinda makes sense that a shaft that is not so straight as the higher end, straighter, more expensive Gold Tips would flex more on impact with the target. Carbon is noted for its memory or its ability to resist a permanent set or go back to its original dimentions but I doubt it can resist forever. Maybe its a lesson on economy of buying better shafts.

I love my goldtips!
