So what's causing the groups to open up? The amount of shooting the arrows or the time since they were manufactured?
Yeah, just what is da problem? [&:] I sure do respect you guys

and now I am getting concerned as I am/was planning to use these on my elk hunt this Sept.
Spine dedregration (sp)
Of the 2 dozen that I brought I put the best dozen aside for hunting.
As of yet I have not had any problems with the dozen I have been shooting well with the exception of one being opened up like a banana[:@] but that was my fault you should never aim at a nock when you have a broad head on the arrow your about to shoot.
I always cut my arrows from both ends with atleast an inch from the nock end it really all depends on how the bare shafts spin. Over the years I have seen some arrows with terrible nock end wobble and if I had those shafts made up in some of the Pro Shops they would have just put the nock in and cut from one end and there is no way you can get an arrow that has a nock end wobble to tune or shoot straight.
Best thing to do with any shafts you get is to spin test them and if you have to get them made up in a Pro Shop make sure they cut from both ends it will cost you a few extra dollars but will save you a lot of headaches in the long run.
