For one thing, Paul, I totally disagree that a high FOC is not good for long range shooting. Arrows with high FOC are supposed to 'nosedive' at long range, according to the guys who subscribe to that theory. Plain and simple, they don't nosedive. Trajectory might not be as flat but that's due to the arrow weighing more, not to the weight distribution of the arrow.
It's another speed cult myth.

Ever played a round of darts? Darts are made with a very high FOC. Try throwing a dart fins first instead of point first and it will flip around and, after a couple of wobbles, will straighten out, quickly stabilize and fly point first. It'll act just like you threw it point first to start with. The heavy end naturally wants to go in front and the light end is perfectly content to trail along directly behind it. I guess somebody with a PhD in physics could explain how it works, but all I need to know is that it works... and it do.
Same deal with arrows. The higher the FOC, the more stable the arrow. The higher the FOC, the quicker the arrow will stabilize when it leaves the bow, or in case of a minor deflection. The more stable the arrow's flight, the more accurate it is. Not to mention the easier it makes bow tuning.
When someone does what Straightarrow does, run a really high FOC then put big ol' feathers in a healthy helical on the back end of the arrow, he winds up with an incredibly stable arrow. It costs some speed and a bit of trajectory, but everything in archery is a tradeoff.
