I'm happy with a rain jacket, wrap and umbrella. Gives you a lot of versatility. Umbrella up for light showers, and it's hands free, so doesn't disrupt my walking. Starting to get constant drizzle add the wrap. Really heavy and or blowy jacket on, but you may be able to leave it undone for ventilation depending on the rain direction. This solution works for me. Umbrella helps cover the top of the pack and the gap between, good to put over the pack whilst setting up, I've brewed under it whilst sitting on a log, good for the late night visits to the privy, etc. Used it on the first 300 miles this year and got quite a few "wish I had an umbrella" comments, in the rain.
