This is a greta arrow for 3-D and hunting. I use Duravanes with the Durvane glue and have no problems with the fletching coming off. I think a consideration you should look at for 3-D is the Carbon Express Line Jammers and the Vapor 23 Speed shaft. Both have the diamneter of a lareg 23 series aluminum arrow yet are a lot lighter.

The extra cutting diameter could com e in real handy on the 3-D course if you have a close shot & need just a fraction more to cut the line!
