I have been shooting them for years (5yrs?). I bought two dozen on sale from 3Rivers. Basically I still have the same 6 in my quiver from the beginning. Well...I broke two. One I missed a rabbit and hit some old farm equipment that was buried in some weeds. The other arrow a doe managed to break right behind the point (last thing she ever did). They are tough, fly like darts, and hit like a ton of bricks.
Using 125gr points, 100gr inserts, CX-HE 250's, 5" feathers.
Get them tuned...and you will not regret getting them.
