902, I had problems last month shooting outdoors with .019 breaking. I had three straight pin fibers break just from shooting. I thought it had something to do with the cold temps. So when I called CJ to see if it was just me they said they where having trouble with the straight pins and fiber breaking and are working on a solution. The other off set fibers seem to be Ok. They sent me some pins and replacement fibers. I also added a amall limbsaver to the sight. So far they been holding up. I've use .019 on my HTM sight with no problems so it might be the shortness of the fibers that cause the problems. They're also coming out with a flip up cover. That will solve the problem with brush breaking the fibers. Jerry
