Heavy Hunter 400s - I have been shooting them out of my longbows since early this year. I bought the shafts at Lost Nation and had Larry cut them for me.
I like the mass of these shafts and they fly excellent out of my bow - even as a bare shaft.
And they are tough! Stumpin' one day, the arrow skipped into a rock pile. Messed up the point good and the nock popped out part way, but I just pushed the nock back in and threaded on a new point - no problems thereafter.
The shafts *are* expensive and I talked to Larry a couple of times, since he himself is shooting them, before pulling the trigger on a purchase of a 1/2 dozen.
I am shooting primarily wood now cause that is what I prefer to hunt with, but I will probably pick up another 1/2 doz. of the Heavy Hitters in the future.
Good luck with your search!
Shoot straight, Shinken
