RE: Brace height vs Axle to Axle length?
According to Chuck Adams in the January 2003 issue of Bow & Arrow. bows with brace heights of 7" or greater tend to be more forgiving. Less than 7" will be a speed bow. A more forgiving bow would be my preference if I were just getting started in archery.
My FX has a brace height of 7 1/2" and shoots at 231 fps and is a tack driver.
