My recollection is that a "normal" spin entry would tumble the gyros in a
150M, but not in a 152. *Apparently, if my recollection of the gimbal limits
is correct, the 150 dipped through 80 degrees nose down on the entry and the
152 did not.

Oh. The 152 goes at least to 80. I'd say inverted through 90, pretty
much, on entry.

It's got a caged gyro but when I've done spins it wasn't caged --
definitely took a tumble.
