When you say washing winterized bho to extract lipids, I assume you mean you are wanting to wash a solution of bho:alkane (hexane or heptane)(nonpolar) with saline (polar).
If that is the case, I prefer Heptane for the reasons @soxhlet mentioned, but also because it has a higher boiling point. This makes it easier to perform a hot #CBleach scrub without evaporating all of my solvent or needing a reflux condenser.
FYI, adsorbent scrubs are significantly more effective after removal of phosphatides. Also, disassociation of said phosphatides with low pH saline is crucial to making them fully water soluble
