Been shootin' 'em for years, its the cheapest shaft you can shoot in my opinion, of any type material. They are bomb proof, takes a direct hit on rock or steel to break 'em. They will be light (about 400 grains with a 125 point) but its easy to fix. Either buy the brass inserts (50 gr and 100 gr) use big heavy points, or the cheapest way..., a .243 cal bullet i'm told fits the shaft perfectly. I don't see the lightweight as a bad thing, just load the point end, you will probably need to anyway to get them to spine right. The 35/55 's are too stiff for my 55# bows, but with a 100 grain insert (or bullet) plus a 125 grain point they spine good cut 29 " to the back of the point. Its fun to play around with them. First determine how heavy you want you're finnished arrow to be. Load the point end with appropriate weight, glue it in,screw on you're field point, then bareshaft it at a bale at 15-20 yards. Its probably gonna be weak spined at this time, no problem, pop out the nock, remove 1/2 " with a dremel hi speed cutting wheel. push the nock back in try again. Keep this up untill you get perfect bareshaft flight, and you can,trust me. You'll never regret using them, just don't let Dennis know.
And I say cast them through the lungs of a deer, then dine on its tasty flesh, like I did last year, the year before, and the year before that.., and so forth, and so on.
