they are advertised in petersons or bowhunter---suppose to be a thinner shaft but consistant heavier spine weight though out--5.5 grns at 30 in with a 70lb bow with 100gr broadhead and vanes.states that they will get 320 ft per sec but because of the spine wt. will penetrate like a 600 gr. arrow anyone seen this

I've seen their 2 page adds. Personally I don't think they are doing much more than trying to sell their arrows based totally on speed. They advertise such speeds because they are so light. Spine may help but I want it proved to me they are getting the kind of penetration they advertise. Just remember one thing...a lighter arrow also slows down faster at longer distances.

Dont forget that at 70 lbs, they will be under 5 grains per lb. Maybe thats why they paired up with High Country Archery. They claim their bows are safe to shoot with only 3 gr/lb. just imagine the bow exploding. [:'(]
