We use sponges pretty regularly in our lab, though have had trouble with them sticking to particularly small and fragile samples. We have switched to using Telfa for the more fragile/delicate samples (works well, although the Telfa is sometimes difficult to cut down to the right size for the cassettes), though we have not tried lens paper before. For most samples, the sponges work well. I just make sure to dip them in the fixative before placing the tissue on them to avoid potential artifacts in the sections.
