Inever said that you stuttered.... I said your comparison is no good and invalid. Everyone cannot just choose a KE "that works for them" and tweak their arrow weight and speed to attain it.

For example "Johnny" has his bow set at 70 pounds shooting 275 feet per second with 67 ft lb KE. How in the hell is he going to "tweak" his bow to shoot that 500 grain arrow the same speed??????

Hello...... Does your comparison make sense now???? NO, it doesn't. There was no misreading or incomprehension...... I see through your BS comparison and pointed out it is a null point. It is unattainable.

Even if "Johnny" had his bow set at 60 pounds, shooting 400 grain arrows at275 feet per second with 67 ft lb KE and he cranked his bow all the way up to 70 pounds............ his bowSTILL wouldn't produce theenergy to push the said 500 grain arrow 275 feet per second. At 60 pounds he would be firing that 500 grain arrow around 240 feet per second. By cranking his draw weight all the way up to 70 poundshe would produce atbest 20 FPS out of his rig...... Leaving him WELL shot of the 275 feet per second you suggested in your post.

Once again your comparison is no good and tomuch of an exaggeration to even be taken half way seriously.

Now what was that I said....... Oh yes, Apples & Oranges.....
Dude, I never realized that you were that simple of mind. My bad. For some reason you and some others are hung up on the "speed" thing. I predict that most of the speed freaks will eventually learn the hard way, that speed is not as helpful as they think.

Some people have bows that go from 70-80 lbs, some 60-70 lbs. Obviously, if you are maxed out in poundage, you can't crank it up anymore. But you can go up in arrow weight and come to a good KE rating. The idea here is to come up with a compromise with all factors of your own personal equiptment and settle on a good solid KE rating for hunting situations. In your example with little Johnny, by him going to a 500 gr arrow and dropping to 260fps, he gets 75 ft-lbs of KE. Good for killing anything in North America. A 12% gain in KE with a 5.5% loss of speed. At shot ranges out to 30 yards for deer, the gain in Ke helps more than the loss of speed hurts. At 30 yards, with the heavier arrow, you lose .018 sec.from time of release until impact. Do you think that will make much difference? I'd take the KEs.

And yes..... People can choose a KE that will work for them within bounds of the equiptment that they are using. Of course a youth shooting 40 lbs. with a 23" draw length cannot obtain 80 ft-lbs of KE, but they can experiment with their equiptment and find a KE that will work best for them. I didn't think that I had to spell out every little detail for you, but now I know better. You do have a keen eye for pointing out the obvious, good job.
