According to your profile, you already have a T-Road Solid?
In any event, if you specifically are wanting the ball to handle higher volumes of oil, the R2X coverstock on the Dimension is stronger than the R2S on the T-Road Solid, so that makes it a better choice. But otherwise, I just punched up a Dimension and am very impressed by the continuous motion it makes once it begins to hook. (It's the most continuous ball I've seen since the Cell, which is saying a lot)
