Yup, rain that goes on is a real drag, but unfortunately comes with the season, so hopefully next time you can choose a better time of year.
You'll also find in warmer seasons that you'll be able to greatly reduce the amount that you bring, and less weight will be more enjoyable to ride with.
Be safe riding in the dark, this is something I've avoided at all costs, have had to a few times, but it simply increases the risks.
your 130am setup is pretty drastic.
