If I run a 45 deg straight helix, should I run a straight 40 in a roller secondary? Just wondering if when running a roller secondary you should generaly lower the angle or increase the angle.

With a roller it will upshift like a 47 and backshift like a 43
It depends whose the manufacterer of the roller is. Some rollers u gotta add 10 degrees & some are the same. All of em are different.
