RE: Big Question About Front Of Center (FOC)
To put it as simply as possible.....An arrow will ALWAYS fly heavy end forward. If the nock end were heavier than the tip, it would turn tails and fly nock forward. Guaranteed. So the closer your balance point is tho the dead center of the arrow, the harder the fletching has to work at keeping it straight.
Move that balance point closer to the nock, and your arrow is MUCH more stable.
In other words, have more weight toward the front than the back.
