Im not trying to start anything, but its not advertising. Its a proven fact. Let off doesn't affect speed on this bow. You could have 50% let off with the same speed as a 90% let off bow. Its all in the lever-lever design. One of our own, IL Rancher, has a Stealth, he will attest to the fact. The guys who build it are not con artists. The Black Eagle I have was built by one of the guys who builds the Stealth. The reason I say "close to" is because they chrono'd it at 70lbs, 350 grain arrow, 29 3/4 inch of draw and they got 328fps. Add the 1/4 inch draw and I don't see why you wouldn't get 330. Again, Im not trying to start anything, just answering your "question." We can take this to PM if you want to talk further, doesnt matter to me. I realize your just watching out for a fellow hunter.
