Crossovers where Hand is Expanding and Contracting

[fftransform]

I don't normally struggle with big leaps or crossovers, but in this one piece the left hand is doing a couple fast ~3 octave crossovers where it's very busy with a narrow hand but leaping down to a wide chord.  It leaps back up immediately; the 'back up' part I don't have misses in, but going down with the hand expanding I'm not consistent on.  And it really hasn't gotten better from just practicing through the piece a lot.

Has anyone else had this issue, any advice?  Basically just 'stuff to try' or 'stuff you heard worked for someone.'

Could you post a picture of the score with the bars in question?

Just asking in general, the exact chord and figures is irrelevant so not gonna say the piece/passage.

I just had trouble picturing exactly what you meant, so I'd find an example from the repertoire helpful. It'd be easier to elaborate a general principle you can apply everywhere using a specific example as a foundation.

Post a snippet of the bars already, talking about it in general is stupid.
