The whole speed thing is great but like the trajectory chart shows its not gonna help you much with the fudge factor past 40 yards or so. The biggest advantage I have found in my setup which shoots a 370grain arrow at 300fps is that I can use my top pin out to about 32 yards and not deviate more than 2inches or so from the bullseye 0 to 32 yards. That makes it real handy not having to worry about judging if that buck is either 23 yards or is he 28 yards, it doesnt matter put the top pin on him and he is done. Of course you could really get things stirred up and start talking about shooting an arrow of 5.5 grains per pound of drawwhich better because its faster than on that weighs 6 or 7 grains. Would that heavier arrow make a difference in penetration over the lighter faster arrow?
