Interesting question . . . I've just started doing the paper-less thing and I'm slowly learning to trust my PDA and realize that computers are my friends (contrary to what I've seen in the Terminator and Matrix movies) so right now I'm about 50-50 when caching.
That said, I suspect I'll be doing more paperless caching as I become more familiar with the PDA.
