If all you want to shoot is roundball, look for a 1-70, 1-66, 1-60 such twist. If you want to shoot roundball and conicals and sabots then a 1-48 or 1-38 might be your best bet. If conical bullets are your thing look for a 1-24, 1-28, or 1-32. If sabots then 1-28 or faster would be the way to go.
I have all of them twists. Which one you want to know about?
