Audiobook Delivery Methods (Patreon)

I've been thinking about how I deliver audiobooks to you guys, and wanted to get your opinions. Due to a combination of my slow upload speed and Patreon's less than stellar upload manager (or lack thereof), I'm not able to upload the complete, zipped audiobooks to Patreon. They always stall out or lose connection before they finish.
For Pinwheel, I used Dropbox, which worked okay, but didn't really justify the subscription fee. I've been looking at other options ready for the Goetic Justice release, and I narrowed it down to MEGA and Patreon.
Uploading to MEGA would allow me to deliver a zip file with all of the chapters and associated content packaged into one file. It would have an encryption key that you'd have to use to access the file, like a password.
I could also upload each individual audio file to Patreon as an attachment, which I've tested, and it does work much more reliably as the individual chapters are smaller. There would be no password required, as it would be accessed via your tier level, but the downside there is that you'd have to download 10+ files individually.
Let me know what you think.
