I think I still have it in the panniers of the commute bike or similar, but
there I have loads of space, and punctures are relatively rare and the mini
pumps I have are fine for that.

Nor from memory was the Morph much better much more mini pump than track
pump, so I just didn’t see the point really I have different mini pumps for
different bikes as some such as the MTB are low psi but large volume so
need to shift a lot of air.
