Remember, the string hand is also rotating as the bow rotates. All should be in the same plane if you aren't commiting some kind of form error.If the bow is upright, the shaft is flexing (mainly) east and west. If you lay the bow over 90 degrees, the shaft will now flex north and south. The same flex and recovery will be required in both positions to get good arrow flight.The flex of the shaft has nothing at all to do with up, down or sideways. The direction of the initial flex is away from your fingers, regardless of whether that means horizontal or vertical.
