I think this has to be my best attempt to date. Used a flip and DR bounding to find this solution. Really proud :D
Maybe bounding is an overstatement, but I started and found the finish immediately.

I guess the new HTR can also be thought of as a DR extension where you insert M2s in a clever way. But clearing out the DR makes it easier to find.
