Thanks for the replies everyone. Nice to log in this morning and have some input from people who truly know their stuff.

To the Daves (both American and English) and country boy, thanks for confirming that only small amount of expo are commonly used..

It took me a bit of thinking through, but it finally dawned on me that using expo on elevator can actually have the opposite effect than intended, during the final flair for landing. At this point (holding nearly full up elevator) the expo curve is working to make the elevator MORE sensitive.
