ORIGINAL: WA Shooter
There is a good post on here about GT's with many guys giving the pro's and con's. I think the majority of guys are happy with them.
I shoot them, and due to my own mistake had trouble getting them to tune. I shoot a '02 patriot at 70# and was trying to shoot the 5575's, I think they are just a bit underspined and am going to try again with some 7595's I aquired.
I think you would be hard pressed to find a more durable shaft.
I shot 5575 GT and had trouble tuning to them also. I have to disagree with throwingstarr. You will be much happier with the 7595 arrow. I am speaking from experience. I realize that GTs chart say the 5575 is ok for your bow but I found it to be too light a spine. Changing tips may work but the heavier spine will definitely help.
