From what I can tell, recency is less critical for non-typed aircraft. When I look at the job boards for say Learjet pilots, recency is always mentioned down to hours per quarter but when I look at Caravan pilots, they often do not mention recency at all. In many cases the training for the non-typed aircraft is done in-house at cost. The types usually have to be maintained at more expensive sims at CAE or FSI, and there is a big disincentive to hire someone who comes in expired because insurance makes them send that pilot on a $10k-$20k trip to the sim. If you are current in a LearJet you might consider it more of a loss to drop out than if you drive a small, non-typed airplane.
