I would consider the following before making your decision.
1) You have a couple newer pieces in your bag, do you know how they react completely yet?
2) Also how similar does your 2D and your Hyroad roll? If close, which one is more consistent or your favorite?
3) How much overlap does the VG, VE, and the Gravity give you? You might be able to drop one based on that?
1st out- Dimension
2nd out- Secret
3rd out- 1) Either the the 2D or Hyroad OR 2) one of the VG, VE, or Gravity
