i just tached my headspeed with the iphone and im getting 4296 at 90 flat curve. might try 100 flat just to see what it is for giggles. im shooting for around 4000 so ima have to play with the curve might try 85. or just keep at 90 if that headspeed is ok to run.
update: i tried 100 flat and it said 4686 so thats a little more than i feel comfortable with dont want to throw a blade or grip into myself
