for years i spined (NBP) at 9:00. read Beasts book and saw he spined at 12:00. i tried one this way. when i FLO'ed the two ways(9:00 vs 12:00) i found the 12:00 FLO'ed better. I've continued to spine at 12:00 and check FLO after the club has cured.
in all honesty, the small variation in head position in a dynamic swing due to spining is much less than the variation in head position due to my swing mechanics, including the variables as to thickness of grass under each foot on the tee box, wind shifts, tiny variations in tee height, thickness of the golf shirt that day, and oh yeah, my swing mechanics and swing path variations.
