well i pulled the two stringers out of the package a couple days ago and was dissapointed after i shoot it in to my foam target,,i pulled it out and the tip was curled over,,only had one do this and it still flies great so i guess i can complain to much,besidesd it is just a practice blade now,,,actully saying that and then saying that they do hold up extremly kinda contradicts waht i just did say but o well,,i shot the metal support rod on one of my other targets and u cant tell that i even hit it with out looking real close at the blabes,,these thing are damn near indestrucable,,i did bend a bleeder blade though,,on the same metal rod that main blade hit,,it still flies extremly well,,even out of a poorly tuned bow,,ohh and as for the rod it has two nice little gouges in it from the main blade and the bleeder
