Has anyone had had any experience with these? Do they have little
drainage holes to let water out? Any other thoughts?

In this picture, the RR 1.1 appears to have no holes nor am I aware of
any rims that have drains. Although it is available for 28..36 spokes,
I don't believe it uses spoke sockets or that would have been shown.
This rim supports spoke loads on eyelets bearing only on its outer wall.
