Whitney, by HF&J ( www.typography.com ) has to be the most legible font I can think of - ever. It’s probably one of my favourites too!

If the text is for extended reading I don’t think a sans, even an excellent one like Whitney will be as readable as a good serif. Fedra Serif, for example, would be a good candidate for small sizes.

If this is a reference like a dictionary or timetable, where one is looking up specific information, and only reading a short bit of it, then a sans may be OK.

For best legibility, stay with serif. The best legibility at 9pt, in my experience, is ITC Stone Serif with oldstyle figures (available from ITC, not Adobe). Also, Sabon, though its x-height is not as big. Stone Serif is a stupendous three-weight workhorse that is not over-exposed. Also, look at Freight Serif, Bitstream Arrus, Celeste, Haarlemmer, Stempel Garamond, and Warnock.

I’ll repost my scientific findings from earlier this year in case they’ll help:

Karmina is economical and indestructible
