I went out for another session with the Lightspeed arrows. This time I switched the 100g points for 75g and the problem disappeared. Now I can also shoot one pin back to 30 yards as well because the arrows don't drop like with the 100g tips.

They really flew well! Not sure if it's a FOC problem with the lighter weight arrow or spine or both. Don't really care because it hits where I aim, consistently!
