These balls are not comparable, the 912T is a lot more ball than the Mission X and Pursuit S. The ball you would probably compare them to is the 811SE. The 912T will be stronger than the other two over each part of the lane. If you want an oiler that doesn't quit then get the 912T, best of all, it doesn't change it's shape with surface modifications you just get more or less hook overall. If this is not what you are looking for than I would suggest you look elsewhere.
